) [static]

Calculates and set the QC parameters relevant for Cosmic Rays.

Parameters:
pre Pointer to XSH_PRE Structure
nbcrh Total umber of cosmics found
nframes Number of frames used to remove cosmics
instrument Pointer to indstrument description structure

< Average of cosmics per frame

Creates median, error and bad pixel map images from a set of frames.

Parameters:
rawFrames Pointer to the frameset (returned from xsh_prepare)
result_tag Tag of resulting file
stack_par parameter to control frame stacking
instr instrument containing the arm , mode and lamp in use
list Pointer to created image list
crh_ima Pointer to created crh image map
save_tmp parameter to control temporary products saving
Returns:
the mean or median frame newly allocated where cosmic-rays are removed by stacking process
