class lsst.cp.pipe.CpMeasureGainCorrectionTask(*, config: PipelineTaskConfig | None = None, log: logging.Logger | LsstLogAdapter | None = None, initInputs: dict[str, Any] | None = None, **kwargs: Any)

Bases: PipelineTask

Task to measure gain corrections.

Methods Summary

run(*, input_reference_flat, ...)

Parameters input_reference_flat lsst.afw.image.Exposure Input reference flat (typically a certified calibration). input_reference_ptc lsst.ip.isr.PhotonTransferCurveDataset Input reference PTC (typically a certified calibration). input_flat lsst.afw.image.Exposure Input flat to derive gain correction (relative to reference flat).
