This folder contains calibrated X-ray data as well as some scripts and plots 
used in preparation of the MNRAS paper "X-ray Spectroscopy of the gamma-ray 
Brightest Nova V906 Car (ASASSN-18fv)" by Sokolovsky et al. 2020.

****###### NuSTAR ######****

 * raw_and_pipelined_data__plus_lightcurves
   - contains the input and results for the NuSTAR pipeline.
   The contents of 80301306002_lev3 and 90401322002_lev3 is used for the
   spectral analysis (see below), while 80301306002_lev3_lightcurvetest and 
   90401322002_lev3_lightcurvetest are produced by the script regenerate_nustar_lightcurves.sh
   and are used to perform the Chi^2 test on the ligtcurves. (The difference
   with the spectral dataset is only in the lightcurve binning time.)
   The folder also includes the code to convert FITS lightcurves to ASCII 
   ( lightcurves__code_NUSTARLC2ASCII ) to feed them to the code performing
   the chi^2 test ( lightcurves__code_for_chi2test ).

 * two_epochs_joint_fit_v999_new_model_with_lower_limit_on_Galactic_absorption__cflux_final
   - contains calibrated NuSTAR spectra for the source and the background
     produced by the NuSTAR pipeline:
   nu80301306002A01_bk.pha
   nu80301306002A01_sr.pha
   nu80301306002B01_bk.pha
   nu80301306002B01_sr.pha
   nu90401322002A01_bk.pha
   nu90401322002A01_sr.pha
   nu90401322002B01_bk.pha
   nu90401322002B01_sr.pha
   as well as the gruped versions of the spectra ready to be imported to XSPEC:
   epoch01_grouped_spec_A.pha
   epoch01_grouped_spec_B.pha
   epoch02_grouped_spec_A.pha
   epoch02_grouped_spec_B.pha
   All the processing is done by the script group_spectra_fit_models_and_make_plots.sh
   that groups the original spectra and fits various models (.xcm files) using XSPEC.
   The input (_xspec_in.txt) and output (_xspec_out.txt) of each SXPEC
   session are saved together with the corresponding plots (.ps and .png).

   
****###### Swift ######****

The folder contains Swift data downloaded from the archive and the results
of running autoswift.sh script that performs per-epoch analysis creating autoswift_results__ASASSN-18fv
and stacked_xrt_observation 
The folder stacks_new contains the observations grouped and stacked into
~50day bins using the same autoswift.sh script. The results of XSPEC 
analysis of the binned Swift spectra are in Swift/stacks_new/allstacks/
