Bad pixels

By default epicproc will try to detect bad pixels for any imaging exposure. The new bad pixels are then used in the data reduction together with any other known (via the calibration files) bad pixels.

The parameter searchforbadpixels controls whether the task badpixfind is run. Further, the parameter searchforbadcolumns controls whether bad columns are also searched for. Both parameters are set to true by default.

A number of parameters are available to modify the way badpixfind operates: thresholdlabel, lothresh, hithresh, columnsearchlabel, locolthresh, hicolthresh, flickertimesteps, flickerksthresh, flickerchisqthresh, backgroundrate, narrowerthanpsf, threshabovebackground, loenergythresh, hienergythresh. Refer to badpixfind for a detailed explanation.
