omvariability (omvariability-1.6) [xmmsas_20230412_1735-21.0.0]

Command-line list of parameters

1. omvariability
   • Use all the OM product source-list files in the current directory as input.
   • Add variability parameters to the OM observation source-list file in the current directory.
   • Store the source-variability plots in omvariability.ps.

2. omvariability plotfile=plot.ps
   • Use all the OM product source-list files in the current directory as input.
   • Add variability parameters to the OM observation source-list file in the current directory.
   • Store the source-variability plots in plot.ps.

3. omvariability minnumcounterparts=5 minstd=3
   • Use all the OM product source-list files in the current directory as input.
   • Add variability parameters to the OM observation source-list file in the current directory.
   • Store the source-variability plots in omvariability.ps.
   • Only compute variability parameters when there are a minimum of 5 counterparts to a unique source and the computed standard-deviation of the corrected count-rate is at least 3..

4. omvariability directorylist=”directory1 directory2 directory3”
   • Use all the OM product source-list files in the directories directory1, directory2 and directory3 as input.
   • Store the source-variability plots in omvariability.ps.
   • A temporary observation source-list file is created by running omsrclistcomb but deleted.

5. omvariability directorylist=”directory1 directory2 directory3” obsset=observation.fits
   • Use all the OM product source-list files in the directories directory1, directory2 and directory3 as input.
   • Create an observation source-list file called observation.fits and add the variability columns to it.
   • Store the source-variability plots in omvariability.ps.
