5.2 Old Releases
5.2.1 Version 10.1
This version was released on or about Feb. 14, 2012. It addresses a number of issues related to the new
wideband system on the VLBA.
-
Add
example
eg3mm_rdbe.key
that
shows
how
to
schedule
reference
pointing
while
doing
RDBE_PFB
observations
where
the
RDBE
cannot
be
told
to
use
the
Doppler
frequencies
and
narrow
bandwidths
needed
for
reference
pointing.
This
involved
adding
the
catalog
files
sources_RDBE_PFB.pointing
and
peak_RDBE.cmd
which
are
very
similar
to
sources.pointing
and
peak.cmd
but
set
up
for
use
when
making
the
RDBE
schedule
(VEX
file).

Add
warning
if
requesting
more
than
0.5
MHz
per
spectral
channel
if
correlating
in
Socorro.
That
puts
the
data
at
some
risk
of
smearing
when
correlated
with
a
priori
clocks.

-
Add
ASC
(Astro
Space
Center
-
Moscow)
to
the
allowed
correlators.
That
correlator
is
used
for
Radioastron
data.

Some
pointing
schedules
driven
from
the
scripts
using
the
optimization
mode
that
takes
scans
that
are
up
were
passing
up
a
lot
of
good
scans
at
the
start.
Itcatalogs/sources.gsfc2011b
turns
out
that
this
was
because
the
estimated
start
time
of
the
first
scan
was
changing
too
much
until
a
scan
was
finally
kept
and
sources
that
were
actually
up
were
flagged
as
down.

Allow
1040MHz
BBC
for
RDBE_PFB
so
it
is
possible
to
schedule
single
polarization
runs
that
span
the
full
IF
bandwidth.
Warn
of
likely
corruption
of
data
in
that
channel.
If
sideband
inversion
is
being
used,
the
528
channel
will
also
be
needed
so
allow
that
too,
but
warn
that
the
on-line
system
will
change
it
to
1040.
Correlation
will
happen
as
if
it
is
1040,
so
don’t
expect
fringes.

-
Make
it
possible
to
write
Vex
files
for
pointing
observations
on
the
VLBA.
This
required
providing
a
FORMAT
in
the
schedules
and
getting
around
some
tests
against
non-recording
projects
in
the
Vex
and
regular
code.
A
future
enhancement
will
be
to
allow
FORMAT=NONE
for
non-recording
observations
and
to
provide
some
way
to
specify
pointing
patterns
in
Vex.
The
immediate
need
is
driven
by
the
transfer
of
control
of
all
switches
on
the
VLBA
antennas
to
the
new
control
system
which
was
originally
meant
to
control
the
RDBE
and
Mark5C
but
will
eventually
control
everything.
The
new
control
system
works
from
the
Vex
files
and
must
control
the
switches
for
all
observing,
including
pointing
type
single
dish
tests.
This
item
also
includes
adding
the
ptv...
setup
file
for
pointing
with
a
FORMAT
assigned.

Make
new
source
catalogs
sources.vlba.2011nov,
sources.rfc2011d,
and
sources.gsfc2011a
based
on
the
Goddard
2011a_astro
and
Petrov
2011d
solutions.
Provide
symbolic
links
sources.vlba,
sources.Petrov,
and
sources.GSFC
so
schedules
don’t
have
to
be
kept
up
to
date
with
last
release.
See
the
top
lines
of
any
of
those
files
for
details
of
how
they
differ.
Users
should
think
about
which
they
wish
to
use
which
is
why
sources.vlba
is
no
longer
there
except
temporarily
as
a
link
to
the
previous
catalog.

Fix
an
oversight
in
the
Vex
code
where
two
FREQ
blocks
could
be
considered
the
same
if
everything
except
the
net
sideband
matches.
We
actually
had
a
test
schedule
involving
sideband
inversion
at
the
GBT
that
had
just
such
a
situation,
when
the
FREQ
blocks
should
not
have
been
condsidered
to
be
the
same.

Fix
a
bug
where,
if
there
were
no
periods
ok
for
preemption,
an
array
element
with
subscript

was
accessed.
The
SUN

did
not
like
that

When
using
the
frequency
catalog
to
find
a
good
first
LO
etc
when
using
the
RDBE,
discourage
choices
that
will
cause
baseband
channels
to
include
a
crossover
point.
This
should
help
get
settings
for
which
the
32
MHz
channels
with
the
PFB
are
at
the
right
place,
even
when
there
are
both
upper
and
lower
sideband
first
LO
choices.
It
also
helps
get
the
right
LO
setting
when
the
DDC
is
used.

Add
warning
when
the

Add
support
for
the
new
VLBA
4-8
GHz
receiver.
Very
many
frequency
options
were
added
to
freq_RDBE.dat
to
support
the
4
channel
IF
converter.
The
use
of
any
of
the
4
IFs
was
added
to
the
checking
routines,
although
the
total
number
is
still
limited
to
2
for
now.
Example
egcwide.key
was
added
to
exercise
this
system.
This
will
still
be
called
the
6cm
band.

For
RDBE/PFB
observations
where
the
sideband
in
the
RDBE
must
be
lower,
allow
for
the
fact
that
the
DiFX
correlator
can
invert
the
sideband.
This
is
done
in
the
code
by
the
program
that
checks
the
setups
for
the
RDBE/PFB.
If
an
upper
sideband
is
found,
it
is
converted
to
lower
with
appropriate
LO
and
sideband
changes.
Some
bugs
were
revealed
in
the
VEX
new
mode
section,
some
of
which
were
fixed,
but
not
all
yet.

These
are
required
for

Cause
the
.sch
file
to
be
written
when
geodetic
segments
are
requested.
This
makes
it
easy
to
reproduce
segments
created
when
they
are
desired
in
another
segement,
such
as
when
making
files
to
test
new
backends.
The
change
in
frequencies
can
cause
freshly
created
segments
to
be
different
due
to
the
frequency
dependent
flagging
of
sources
close
to
the
Sun.

Modify
the

5.2.3 Version 9.4
This version brings in many new capabilities including support for multiple phase centers on the DiFX
correlator, automatic insertion of geodetic segments (DELZN), enhancement to DWELL to
allow scans to start before the slowest antennas arrive, and support for the new wideband
hardware (RDBE and Mark5C with hooks for the DBBC). The release will likely be on Jan. 14,
2011.

When
using
the
RDBE/MARK5C,
make
it
optional
to
have
the
crd

provide
the
commands
needed
for
parallel

DAR/MARK5A
recordings.
The
switch
is
DOMKA
(read
DO-MARK5A).
This
is
expected
to
be
of
use
mainly
for
testing.
A
tricky
part
of
this
was
making
the
pulse
cal
tone
detection
commands
come
out
right
when

This

One
impact
is
that

have
scan
times
that
differ
from
old
ones
made

Added
second
and
third
arguments
to
DWELL
to
instruct
SCHED not
to
wait
for
some
number
of
antennas.
The
second
argument
says
how
many
antennas
to
not
wait
for
while
the
third
gives
a
minimum
integration
time
for
those
last
antennas.
Adding
this
capability
triggered
a
considerable
reworking
of
the
code
related
to
scan
timing
and
geometric
calculations.
The
code
is
somewhat
cleaner
now.
SCHED now
removes
a
station
from
a
scan
if
the
slew
is
so
long
it
will
not
get
there
before
the
end.
An
exception
is
for
scans
that
trigger
an
azimuth
wrap
for
ALTAZ
antennas.
It
was
found
that,
if
those
scans
were
dropped,
the
antenna
could
get
stuck
observing
only
one
source
for
a
while
in
a
phase
referencing
situation
when
one
source
needs
the
wrap
before
the
other.
A
“W”
flag
was
added
to
the
“UP”
flags
to
indicate
a
scan
where
the
antenna
will
not
get
to

When
writing

for
the

the

are
using
FORMAT=NONE
so
they
cannot
be
used
for

The

of

make
it
difficult
to
write
both
crd

appropriate
for
the
old

and
Mark5A
and
RDBE/Mark5C
files
at
the
same

If
parallel
recording
is
desired,
a
Mark5A
schedule
should
be
written
to
control
the
old
hardware
and
a
RDBE/Mark5C
schdule
should
be
written
to

Both

When

5.2.10 Version 6.04
Version 6.04.1 is version 6.04 except that a the sources.vlba catalog has been fixed to remove duplicate
aliases and to restore a very small number of aliases that were lost in 6.04.
The major enhancement in the 6.04 version is the addition of OPTMODE=HAS which can be used to
construct certain kinds of schedules automatically from an input schedule that is basically a source list.
In this mode, SCHED tries to spread the scans on each source in hour angle subject to various
constraints. In its current form, it is most useful for scheduling survey type observations. Future
enhancements will make it more useful for phase referencing and other modes. For more information,
see the OPTMODE description.
This release includes everything that was in the 6.03 mini-releases that occurred since 6.02. Those
mini-releases were not sent to the broader community and were intended mainly to make available the
new OPTMODE=HAS for use by the VIPS survey, which started before we could do a proper SCHED
release.
Change log:
Version 6.04.1:
-

aliases

The

of
the

RCW.
-
SCHED was
claiming,
in
the
summary
file,
that
some
setup
files
were
identical
when
they
were
not.
The
problem
was
a
typo
in
the
channel
index
when
comparing
channel
dependent
data
such
as
firstlo.
The
typo
has
been
fixed.
The
machine
readable
schedules
produced
by
SCHED to
be
sent
to
the
antennas
were
not
affected.
Fixed
3
Apr
2005
RCW.
-
For
Mark5
observations,
SCHED was
complaining
when
there
were
too
few
tracks
even
if
the
setup
was
only
for
non-recording
scans
such
as
those
meant
for
reference
pointing.
This
test
is
now
bypassed
for
non-recording
situations.

Brisken’s
advice.
The
data
will
be

Give
information
in
the

about

time
lost
to
correlator

Warn
users
when
the
latter
is
over
10
percent
of
the
total
scan
time.
We
have
seen
some
projects
lately
where
unfortunate
frequency
choices
in
band
switching
projects
led
to
many
reconfigures
and
massive
data
loss.
In
the
process,
time
lost
to
resyncs
after
tape

is
also
calculated
and
a
warning
is
issued
if
it
is
excessive.

First
Mac
OS
X
installation.
The
main
difficulty
was
getting
PGPLOT
installed.
Later
this
became
easier
if
you
could
get
the
as-yet-unreleased
version
5.3
of
PGPLOT
which
includes
Mac.
Since
the
compiler
is
g77
and
the
underlying
operating
system
is
unix,
the
only
changes
needed
to

were
a
couple
of

in

-
Added
satellite
tracking.
This
was
a
big
change
involving
incorporation
of
the
NAIF
software
from
JPL.
However
it
is
not
expected
to
be
of
general
interest
and
there
is
a
stub
available
in
the
makefile
to
avoid
needing
NAIF.
With
this
change,
SCHED can
calculate
the
position
of
spacecraft
if
a
SPICE
file
is
available.
Note
that
there
is
an
inconsistency
in
the
handling
of
diurnal
parallax
that
makes
SPICE
planet
positions
come
out
somewhat
different
from
positions
based
on
the
JPL

Don’t

This
was
causing
a
problem
when

both
“normal”

“alternate”
IFs
to
try

keep
all

converters.
This
was
requested
by
the
EVN
because
some

maintain
the
first
8
VCs
better
than
the
rest.
A
side
effect
of
the
logic
used
to
accomplish
this
effect
is
that
dual

will
only
use
the
“normal”

5.2.17 Release of 12 February 2001.
It seems that we are having teething problems with the new reference pointing capabilities.
This release makes available some important fixes required for 3mm VLBA projects. But
it does not have some fixes for VEX problems that will affect CMVA runs. So there will
be another release in a couple of weeks. The changes here are not significant for users not
attempting reference pointing with AUTOPEAK or other mechanism that invokes setup files with
FORMAT=NONE. If you don’t need this one right now, it is recommended you wait for the VEX
fixes.

5.2.18 Release of 30 January 2001.
This was an emergency release to fix the problem with the Doppler calculations when using the
automatic reference pointing scan insertion. This problem would be fatal for schedules using

affected.

Add
automatic

This
works
for
the
VLBA

It
is
aimed
as
simplifying

It
works
on

simply
by

For

it

be

This
change
was
triggered
because
the

From

“The
main

is
that
the

can
now
deal
with
more
complex

There

that
used
certain

in
different

in
different

that

not

That
is
now
all
resolved,
but
the
price
was
that
I
had
to
maintain
a

of

for

use
has
increased
a

From

Another

28
Oct

-
Set
up
for
defaulting
many
SETUP
parameters
based
on
input
from
a
frequency
catalog.
This
was
a
major
change
involving
considerable
additional
code
and
a
new
input
file
which
is
called
freq.dat
in
the
catalogs
subdirectory.
If
users
are
observing
a
frequency
covered
by
the
frequency
catalog,
they
only
need
to
specify
generic
information
like
observing
frequency,
polarization,
number
of
bits
per
sample
etc.
SCHED can
then
fill
in
all
the
site
dependent
parameters
like
firstlo,
synthesizer
settings,
channel
names
etc.
This
should
greatly
simplify
the
process
of
making
setup
files.
See
the
frequency
catalog
section
for
a
lot
more
information.
SCHED also
uses
the
frequency
catalog
information
to
check
any
setups
provided.
If
it
does
not
recognize
the
setup,
it
will
complain.
For
VLBA
observations,
this
probably
means
there
is
a
problem.
For
other
sites
with
less
complete
information
in
the
frequency
catalog,
it
is
just
a
flag
to
be
careful
with
what
you
are
doing.
In
the
process
of
making
these
changes,
it
became
possible
to
specify
multiple
stations
for
a
setup
group
(SETSTA
now
has
two
indices).
With
only
the
generic
parameters
specified,
this
can
be
useful.
Internally,
SCHED expands
such
a
case
to
have
a
separate
group
for
each
input
station
before
adding
all
the
LO
values
etc.
After
that,
only
the
first
station
of
the
list
is
used.

5.2.32 Release of 22 Feb 1996
This is a slightly modified version of the SCHED that was released within NRAO in December
1995.
This version included a number of evolutionary changes made up to November 1995. In that
month, the VLBA OBSERVE (GNOMES) project was cancelled and it became clear that
SCHED had much more of a future than expected. Many changes, including addition of
plotting and dwell time scheduling, along with massive changes in internal structure for both
maintainability and for eventual Mark IV support, were made. Also the help file was renamed
the manual, formated for LaTeX and html, and to a large degree, rewritten. It is now this
document.
The evolutionary changes before November 1995 were:
-
Add
REMARK
to
valid
parameters
in
source
catalog.
Someday,
print
it
in
the
summary
file.
(1995
May
31)
-
First
parallactic
angle
was
PA2,
not
PA1,
in
PRTSCH.
Fixed.
(1995
June
4)
-
Added
horizons.
(1995
June
17)
-
Warn
if
automatic
tape
allocation
requested.
(1995
June
26)
-
Rewrite
optimization
mode
routines
for
easier
modification.
(1995
June)
-
Increase
maximum
number
of
setup
files
to
50.
(1995
June
25)
-
Make
cover-like
info
in
VLA
observe
file
look
like
what
VLA
OBSERVE
observe
makes
so
observe
will
read
it.
(1995
July)
-
Fix
rounding
of
F6
numbers
for
VLA,
since
did
wrong
thing
when
negative.
(1995
October
3)
-
Change
reference
pointing
at
VLA
from
IA
to
IR
mode.
Also,
only
put
pointing
request
in
VLBA
control
files
if
this
is
not
a
DAR-only
station
(1995
October
4)
-
Update
some
bits
of
VLA
info
in
help
file.
A
major
review
of
the
help
file
should
be
done
soon.
Also
put
the
help
file
in
HTML.
(1995
October
4)
-
SCHIN
had
FASTF
instead
of
FASTFOR
as
per
the
documentation.
Change
to
FASTFOR.
(1995
October
30)
The big rewrite included:
-
Added
plotting.
-
Added
dwell
time
scheduling.
-
Added
new
subroutines
for
setting
up
and
reading
KEYIN
variables.
It
is
now
much
easier
to
add
and
remove
parameters.
Also,
the
number
of
inputs
for
arrays
is
now
sensitive
to
the
parameter
statements.
-
Much
restructuring
of
code.
-
Can
now
write
telescope
output
files
when
optimization
used.
Optimization
much
better
integrated
into
program.
-
Help
file
made
into
a
manual
and
formated
for
LaTeX.
-
Manual
made
convertable
to
html
by
latex2html.
-
Reduced
maximum
stations
and
scans
parameters.
Some
variables
with
both
dimensions
were
added
so
this
keeps
the
size
down.
-
Convert
many
time
parameters
to
fractional
days
from
radians
inside
program.
Not
visible
to
user.
-
Allow
in-line
setup
files
much
like
the
source
and
station
catalogs.
-
Setup
files
are
now
required
for
all
projects.
-
Allow
a
“default”
station
in
setup
files
(eg
for
Mark
II
or
experiment
planning).
-
Relative
order
of
“VLBA”
default
station
and
any
specific
stations
in
a
setup
file
no
longer
matters.
-
SCHED
no
longer
takes
the
number
of
channels
from
the
main
input
file.
This
is
set
only
in
the
setup
file.
-
The
bandwidth
is
no
longer
required
in
the
main
file
for
observations
using
Doppler
calculations
—
it
is
obtained
from
the
setup
file.
It
can
still
be
changed
in
the
main
file.
-
The
formats
of
the
summary
and
sch
files
were
changed
somewhat.
-
SUN
proximity
warnings
no
longer
overwrite
other
comments.
-
For
dwell
time
scheduling,
more
general
axis
limits
and
slew
rates
were
put
in
the
station
catalog.
Parameter
HALIM
was
removed.
-
In
the
summary
and
sch
files,
scans
below
the
horizon
but
above
the
slew
limits
are
marked
differently
from
scans
below
the
slew
limits
-
Scan
timing
specification
was
enhanced.
GAP
was
added
to
take
the
place
of
the
usual
use
of
PRESCAN.
PRESCAN
is
now
just
a
tape
start
offset.
It
can
be
negative
for
prestarting
tapes.
The
changes
are
backward
compatible
-
SCHED internally
calculates
XYZ
for
stations
if
they
are
needed.
Mainly
used
in
u-v
plotting.
-
Put
summary
file
output
early
enough
in
program
that
it
is
done
and
closed
before
plotting
begins.
It
can
then
be
examined
during
plotting.
-
Now,
when
there
is
in-stream
input
such
as
tape
initialization,
source
and
station
catalogs,
line
frequencies,
or
setup
information,
SCHED
reads
that
input
and
then
returns
to
reading
input
for
the
current
scan.
No
scan
initialization
is
done.
Thus
these
in-stream
inputs
can
go
anywhere.
The
main
use
of
this
will
probably
be
to
put
the
cover
information
at
the
top
of
the
file.
Another
use
is
to
put
in-stream
setup
information
in
the
main
file
at
the
scan
where
it
is
first
used.
This
is
useful
especially
for
test
observations.
-
Let
OPMINANT
and
OPMINEL
apply
regardless
of
optimization.
They
are
useful
especially
in
planning.
-
The
TPRATE
parameter
was
removed.
-
Allow
program
restart
from
plotting
input.
-
Allow
setups
with
different
numbers
of
tracks.
This
can
waste
tape
because
the
tape
management
will
be
done
as
if
all
scans
used
the
maximum
number
of
channels.
-
Allow
specification
of
schedule
input
file
name
from
main
input.
This
allows
one-time
inputs,
such
as
the
request
to
plot,
to
be
made
before
sending
SCHED
off
to
get
the
schedule
input.
-
Add
DEBUG
which
turns
on
some
extra
printing.
-
VLABAND
and
VLABW
were
moved
to
the
setup
file.
-
Added
a
toggle
concept
for
many
variables
such
as
RECORD,
TSYS,
DOPPLER,
etc.
Now
they
are
paired
with
a
NO...
(eg
NORECORD)
that
turns
them
off.
-
Added
OPSTYPE=VLA
for
pure
VLA
observations.
This
helps
tell
SCHED
not
to
worry
about
tape
related
stuff.
-
Changed
DOPCAL
to
DOPPLER
to
avoid
the
confusion
with
DO
PCAL.
Added
NODOP
to
turn
it
off.
-
Got
latest
SLALIB
and
updated
a
couple
of
places
where
there
were
changes.
Also
got
email
permission
to
use
it.
-
Add
OVERWRIT
to
allow
sched
to
overwrite
old
files
if
desired.
This
is
not
the
default
as
a
safety
measure.
-
Adding
CSUB
optimization
mode.
The
optimizes
sky
coverage.
It
includes
subarrays.
-
Adding
SUMITEM
input
to
allow
specification
of
what
is
in
the
summary
file.
-
Changed
XY
mount
type
to
XYNS.
Should
add
XYEW.
-
When
the
station
catalog
is
read,
the
position
both
in
geodetic
longitude,
latitude,
and
elevation
and
in
geocentric
X,Y,Z
are
determined
from
the
information
provided.
The
catalog
should
contain
one
or
both
of
the
above
coordinates.
The
conversion
is
accurate
at
the
cm
level
for
coordinates
in
WGS84.
-
Added
Station
XYZ
to
summary
listing.
-
Allow
vlba
and
vla
defaults
in
TAPEINI
section.
