Find and fix bad pixels in image with median of surrounding values
Paramters
- imndarray
Single image
- sigclipint
How many sigma from mean doe we fix?
- niterint
How many iterations for sigma clipping? Ignored if bpmask is set.
- pix_shiftint
We find bad pixels by comparing to neighbors and replacing. E.g., if set to 1, use immediate adjacents neighbors. Replaces with a median of surrounding pixels.
- rowsbool
Compare to row pixels? Setting to False will ignore pixels along rows during comparison. Recommended to increase
pix_shiftparameter if using only rows or cols.- colsbool
Compare to column pixels? Setting to False will ignore pixels along columns during comparison. Recommended to increase
pix_shiftparameter if using only rows or cols.- cornersbool
Include corners in neighbors? If False, then only use pixels that are directly adjacent for comparison.
- bpmaskboolean array
Use a pre-determined bad pixel mask for fixing.
- return_maskbool
If True, then also return a masked array of bad pixels where a value of 1 is “bad”.
- verbosebool
Print number of fixed pixels per iteration
- in_placebool
Do in-place corrections of input array. Otherwise, return a copy.
