Future developments

As the pattern recognition is a time consuming part (however, much less than the CTI correction) of epevents, the user might not want to repeat this if e.g. the calibration changed. If the parameter patternanalysis is equal `no', the epevents task will be restarted only after the pattern analysis. The parameter is not active yet.

The rejection of MIP events can be done as part of the on-board event processing. This results in a rejection of columns where such events have been detected. The discarded lines information (from onboard CR detections) is the sum over several (default 20) frames. For full correction epevents, however, would need this information per CCD/quadrant and frame for its pattern analysis. Therefore depending on on-board preprocessing the pattern products from epevents can have higher or lower quality.
