Updating
the
manual.
Make
sure
the
parameter
summary
lists
are
complete
because
they
have
become
more
important
now
that
we
don’t
have
the
latex2html
indices.
Make
sure
all
the
example
files
are
listed
(they
weren’t).
Update
the
release
instructions
in
the
manual.
The
manual
probably
still
has
out-of-date
sections
as
much
has
been
changing.

Modify
the
Newstd
script
in
the
examples
area
to
change
various
constructs
like
-0.0
in
the
sch
and
sum
files
to
prevent
spurious
diffs
when
running
the
Verify
script
that
checks
the
output
of
all
the
example
schedules
against
previous
outputs
that
are
thought
to
be
good.

GSFC
(David
Gordon)
is
now
providing
a
locations
file
in
KEYIN
format.
That
is
now
placed
in
the
catalogs/Master_NRAO
directory
and
combined
with
other
locations
files
to
make
locations.dat.
Conversion
from
geodetic
formats
is
no
longer
needed.

SCHED has
long
come
with
a
combined
source
catalog,
sources.vlba,
that
contained
sources
from
JVAS,
an
old
VLA
calibrator
list,
the
GSFC
solutions,
the
Petrov
RFC
solutions
and
possibly
others.
Creating
the
combined
list
has
been
a
somewhat
painful
job,
especially
when
the
input
catalog
formats
change.
Now
both
Goddard
and
Petrov
are
providing
ready-to-use
catalogs,
and
those
catalogs
have
many
thousands
of
sources
so
the
need
for
the
combined
catalog
is
mostly
gone.
Plus
the
remaining
non-geodetic
sources
are
likely
not
good
VLBI
sources.
Producing
the
combined
catalog
was
always
a
chore
for
reasons
that
were
rarely
forseen.
I
have
now
retired
and
no
longer
will
be
able
to
support
the
combination,
so
it
has
been
abandoned.
The
latest
files
from
GSFC
and
Petrov
will
be
kept
in
$SCHED/catalogs
in
files
whose
names
indicate
the
solution
they
are
from.
There
are
symbolic
links
called
sources.gsfc
and
sources.rfc
which
can
be
used
to
avoid
having
to
keep
up
with
the
release
names.
The
examples
have
been
converted
to
use
one
or
the
other
of
these
catalogs.
The
GSFC
file
contains
a
number
of
aliases
for
the
popular
sources,
so
if
you
want
to
use
familiar
names
like
3C273
or
DA193,
use
it.
The
RFC
catalog
just
has
the
J2000
and
1950
names.
The
RFC
catalog
has
far
more
sources
—
over
9000
in
the
2015feb
version
—
so
it
may
be
the
more
productive
place
to
look
for
nearby
calibrators.

Craig
Walker
-
While
looking
at
the
new
source
catalogs,
I
realized
that
RAERR
has
not
been
conforming
to
what
was
described
in
this
manual.
The
manual
claimed
that
the
error
was
in
mas
of
angular
error
on
the
sky.
In
practice,
it
has
been
mas,
but
in
coordinate
error.
Note
that
the
RA
coordinate
is
in
time
seconds,
so
the
reported
error
(mas)
would
need
to
be
divided
by
15
to
get
the
actual
coordinate
error
in
the
coordinate
units.
To
get
the
angular
error
from
the
coordinate
error,
the
value
needs
to
be
divided
by
cos(dec).
Rather
than
change
the
catalogs,
the
description
of
RAERR
in
the
manual
was
changed
to
say
that
it
is
the
coordinate
error
in
mas.

GSFC
(David
Gordon)
is
now
providing
their
source
data
in
KEYIN
format
which
can
be
used
without
conversion.
The
catalog
has
multiple
aliases
for
many
of
the
popular
or
well
known
sources.

Craig
Walker
-
Leonid
Petrov
has
provided
his
Radio
Fundamental
Catalog
(RFC)
in
KEYIN
format
for
some
time.
But
we
have
now
arranged
so
that
we
no
longer
make
any
modifications.
It
can
be
used
as
sent.
It
has
over
9000
sources
in
the
latest
version
so
is
a
good
place
to
look
for
nearby
calibrators.

We
are
making
corrections
to
the
TLE
ephemeris
based
satellite
tracking
to
get
it
to
agree
with
bsp
based
tracking.
Walter
Brisken
is
testing
and
getting
advice
from
Jon
D.
Giorgini
at
JPL.
RCW
is
adding
the
code
to
sattle.f.
Feb.

-
Updating
the
NAIF
software
for
satellite
tracking
to
version
N0065
from
N0056.
This
is
needed
by
an
upcoming
project
because
some
input
files
have
changed
format.
While
at
it,
the
GFORTRAN
version
of
the
libraries
were
generated
so
now
we
can
build
the
satellite
capable
SCHED with
GFORTRAN.
That
is
likely
to
become
the
main
version
shortly.

The
HTML
version
of
the
manual
had
been
derived
from
the
schec.tex
latex
file
using
latex2html.
But
that
program
is
no
longer
supported
and
has
proven
problematic
to
use
with
the
latest
latex
code.
Therefore,
the
manual
was
modified
to
work
with
pdflatex
and
htlatex
to
produce
both
pdf
and
HTML
versions.
Help
for
this
was
obtained
from
John
Shipman
and
William
Colburn
(Schlake)
of
NRAO.
Completed

-
Implemented
the
use
of
TLE
(Two
Line
Ephemeris)
files
for
satellite
tracking.
This
made
use
of
a
subroutine
much
like
SATEP
that
was
provided
by
Walter
Brisken.
Inside
SCHED,
there
is
little
difference
between
using
the
TLE
files
and
the
Spice
files
(.bsp)
files
we
have
been
using
for
satellites.
The
use
of
a
TLE
file
is
triggered
by
providing
a
TLEFILE
rather
than
a
SATFILE
in
the
SATINI
section.

Force
MarkIV
format
setups
for
disk
stations
to
use
TAPEMODE=1.
This
means
that
there
is
one
pass
per
”head
position”.
Head
position
is
a
tape,
not
disk
concept.
A
Radioastron
project
somehow
had
tried
to
use
two
passes
per
head
position
for
a
MarkIV
station.

A
bug
in
the
setting
of
pcalx
frequencies
for
the
VLBA
legacy
system
was
found
by
operations.
It
affected
setups
with
multiple
IFs
with
different
IF
sidebands.
In
fixing
that,
another
bug
was
found
that
affected
frequencies
set
for
the
VLBA
legacy
system
channels
when
the
sideband
inversion
option
was
being
used
(the
option
that
allows
different
stations
to
use
different
IF
sideband
but
the
same
BBC
sideband
as
is
required
for
PFB
observations
with
Green
Bank
at

Change
the

Convert

New

The

sufficiently
generic
that
they

use

when
the
main

not
the

The

The

the

Modified
the

for

MARK5C
system
to
reflect
the
fact
that
they
don’t

in

rather
than
the
specified

time
that
has
been
used
by

The
calculation
for
the
MARK5A

still
depends
on
the

time.
Note
that
the
media
start
time
is
the

is

Fix

Add
elevation
of
skipped
scan
when
scheduling
one
station
at
a
time.
Meant
for
pointing
observations
when
there
is
a
question
about
why
too
many
scans
are
being
skipped.

When
the
IF
sideband
is
lower,
set
the
synthesizer
frequency
in
the
crd
file
to
negative.
This
is
the
ruse
we
are
using
to
convey
the
IF
sideband
information
to
the
VME
on-line
system
at
the
VLBA
sites.
Previously,
it
could
always
be
figured
out
from
the
band
name
and
synthesizer
setting.
But
the
new
6cm
(4-8
GHz)
receivers
have
made
it
possible
for
the
sideband
to
be
ambiguous.

When
making
a
RDBE
schedule,
the
pulse
cal
tone
detection
for
the
artificial
channels
created
for
the
VLBA
old
backend
was
being
set
up
for
the
wrong
frequencies
in
some
cases
(lower
sideband
IF).
Fixed.

There
were
some
issues
with
the
wrap
calculation
when
different
antennas
were
scheduled
separately.
Fixed,
I
hope.

The
DDC
will
use
frequencies
that
require
more
digits
than
the
usual
10kHz
steps.
In
the
output
files,
make
the
number
of
digits
sensitive
to
the
number
required.

Fixed
a
rarely
encountered
bug
when
making
optimized
schedules
when
they
stopped
on
the
first
scan
of
a
particular
planet
or
satellite.
Found
in
a
pointing
run.
