CpSkyImageTask¶
CpSkyImageTask
preprocesses exposures after IsrTask
to mask detections so a cleaner background estimate can be measured.
Processing summary¶
CpSkyImageTask
runs these operations:
Run
MaskObjectsTask
to identify and mask sources in the image.Construct a single-detector
FocalPlaneBackground
model from the detection clean image.
