This task takes an existing eventlist produced by emchain, epchain, emproc, epproc, or the XMM Pipeline (PPS), applies one of the two selectable methods, produces a GTI file, then creates a) a filtered event list, b) filtered image, c) FOV lightcurve, and d) a 'Corners' (corner pixels of outer chips) lightcurve. A QDP plot of the count rate histogram is created by the histogram method only. The QDP file must be converted to postscript or other forms by the user.
