SerialOverscanCorrectionTask#

class lsst.ip.isr.SerialOverscanCorrectionTask(statControl=None, **kwargs)#

Bases: OverscanCorrectionTaskBase

Correction task for serial overscan.

Parameters#

statControllsst.afw.math.StatisticsControl, optional: Statistics control object.

Methods Summary

run(exposure, amp[, isTransposed])

Measure and remove serial overscan from an amplifier image.

Methods Documentation

run(exposure, amp, isTransposed=False)#

Measure and remove serial overscan from an amplifier image.

exposurelsst.afw.image.Exposure: Image data that will have the overscan corrections applied.
amplsst.afw.cameraGeom.Amplifier: Amplifier to use for debugging purposes.
isTransposedbool, optional: Is the image transposed, such that serial and parallel overscan regions are reversed? Default is False.

Result struct with components:

imageFit: Value or fit subtracted from the amplifier image data (scalar or lsst.afw.image.Image).
overscanFit: Value or fit subtracted from the serial overscan image data (scalar or lsst.afw.image.Image).
overscanImage: Image of the serial overscan region with the serial overscan correction applied (lsst.afw.image.Image). This quantity is used to estimate the amplifier read noise empirically.
overscanMean: Mean of the fit serial overscan region.
overscanMedian: Median of the fit serial overscan region.
overscanSigma: Sigma of the fit serial overscan region.
residualMean: Mean of the residual of the serial overscan region after correction.
residualMedian: Median of the residual of the serial overscan region after correction.
residualSigma: Mean of the residual of the serial overscan region after correction.
