CpSkyScaleMeasureTask

CpSkyScaleMeasureTask merges the lsst.pipe.tasks.background.FocalPlaneBackground models generated per-detector into a single full-focal plane model.

Processing summary

CpSkyScaleMeasureTask runs these operations:

1. Merges per-detector models together.

2. Measures the median of the model statistics image to determine the per-exposure scale factor.
