omvariability (omvariability-1.5) [xmmsas_20211130_0941-20.0.0]
This program computes variability statistics (chi-squared and
the maximum deviation from the median corrected count-rate) and
produces light-curves from an input list of OM product
source-list (SWS) files. The source-lists can come from
more than one observation, and for each set of source-lists
in a particular observation omvariability will compute short-term (hours to days
depending on how many exposures) variability parameters for sources that have two
or more detections in a given OM filter. In the case where the input list of
source-lists come from more than observation, omvariability will also compute
long-term (years) variability parameters for unique sources that have been detected
in two or more observations.
The given output file, which has to be an OM observation source-list file, is then
modified by having variability columns added for each filter.
If desired,a plot file of the “variable” sources can be produced.
