The task lccorr takes, as its input, source and (optionally) local-background timeseries (TS) created by evselect, in which the time variation of the flux is represented by counts within time bins of equal duration. The main task of lccorr is to correct these time series for losses in flux due to a number of causes (exposure correction); these corrections are described in subsections 3.3 and 3.4. In addition, lccorr performs several other operations on these TS, which are described in subsection 3.5.
