rgslccorr is the task that allows the user to create RGS lightcurves. The task corrects the lightcurve from:
This task needs as mandatory input parameters a RGS event list, the corresponding RGS source list and a timebinsize. It is also possible to create a lightcurve of the two intruments(RGS1+RGS2), if the two events list belong to the same observation and the two instrument exposure were taken simultaneously.
rgslccorr filters the event list file using the source and background region from the source list file and wavelength range or selects a range of CCDs, in case they were enabled. Then, it creates a time serie, corrects for dead time, exposure and backscal. Finally, the source time serie is background subtracted if the user activates the corresponding parameter.
If background subtraction option is enabled, rgslccorr task creates an independent background light curve file and also created two columns BACKV and BACKE (background rates and errors) in the background corrected light curve.
