Applies median filter for MIPS-Ge data on data cube of stacked BCDs images by subtracting median of the surrounding DCEs (nn) per pixel while preserving spatial scales by ignoring nearest DCEs (ss) (temporal median filter per pixel).

The code is called as follows:

IDL> medfiltss,INcube,nn,ss,OUTcube

where
INcube = stacked cube of bcd images
OUTcube = median filtered output cube
nn = full width filter size in DCEs
ss = full width of saved spatial scale in DCEs

Applies median filter for MIPS-Ge data on data cube of stacked BCDs images by subtracting median of the surrounding DCEs (nn) per pixel while preserving spatial scales by ignoring nearest DCEs (ss) (temporal median filter per pixel)

Users need to stack input BCDs into a cube before running. After medfilt correction, users need to split OUTcube into corrected BCDs and attach pointing information (headers) from the original BCD images before mosaicing the data. For small nn, users should not include the stim DCEs in the input data cube.

Running median from for DCE=zz calculated from:
[zz-nn/2 --> zz-ss/2] and [zz+ss/2 --> zz+nn/2]
