CpFlatMeasureTask¶
CpFlatMeasureTask
measures image statistics from the input flat field frames to supply the information needed for CpFlatNormalizationTask
to determine approprate scale factors.
Processing summary¶
CpFlatMeasureTask
runs these operations:
Optionally masks the vignetted region.
Measures detector level clipped mean, clipped sigma, and number of pixels.
Measures the same statistics at the amplifier level.
