... This task takes an event list and makes an image in which the value in each pixel is proportional to the variability with respect to time of the flux of events which fall within that pixel. The task cycles through all the events in the list which fall within the spatial extent of the image; for each of these events, a value of the Kolmogorov-Smirnov statistic is calculated. ... Note the implication that pixels having zero variability are not zero-valued in the output image. ...

The FOC Exposure Simulator, FOCSIM, provides the capability to simulate almost any FOC exposure and to calculate diagnostics about the image. FOCSIM, the FOC exposure SIMulator, uses the most current description of the FOC and its filters along with an input spectra (either from an on-line catalog or user-supplied file) to simulate an image from the FOC and provide the count rate within the image. ... Where to Find FOCSIM . ... How to run FOCSIM . ... What Sources can FOCSIM Simulate . ...
