lsst.ip.isr.isrTaskLSST.IsrTaskLSST.countBadPixels | ( | self, | |
exposure | |||
) |
Notes ----- Reset and interpolate bad pixels. Large contiguous bad regions (which should have the BAD mask bit set) should have their values set to the image median. This group should include defects and bad amplifiers. As the area covered by these defects are large, there's little reason to expect that interpolation would provide a more useful value. Smaller defects can be safely interpolated after the larger regions have had their pixel values reset. This ensures that the remaining defects adjacent to bad amplifiers (as an example) do not attempt to interpolate extreme values.

lsst.ip.isr.isrTaskLSST.IsrTaskLSST.darkCorrection | ( | self, | |
exposure, | |||
darkExposure, | |||
invert = False |

) |
Apply dark correction in place. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to process. darkExposure : `lsst.afw.image.Exposure` Dark exposure of the same size as ``exposure``. invert : `Bool`, optional If True, re-add the dark to an already corrected image. Raises ------ RuntimeError Raised if either ``exposure`` or ``darkExposure`` do not have their dark time defined. See Also -------- lsst.ip.isr.isrFunctions.darkCorrection

lsst.ip.isr.isrTaskLSST.IsrTaskLSST.doLinearize | ( | self, | |
detector | |||
) |
Check if linearization is needed for the detector cameraGeom. Checks config.doLinearize and the linearity type of the first amplifier. Parameters ---------- detector : `lsst.afw.cameraGeom.Detector` Detector to get linearity type from. Returns ------- doLinearize : `Bool` If True, linearization should be performed.

Extract common calibration metadata values that will be written to output header. Parameters ---------- calib : `lsst.afw.image.Exposure` or `lsst.ip.isr.IsrCalib` Calibration to pull date information from. Returns ------- dateString : `str` Calibration creation date string to add to header.

lsst.ip.isr.isrTaskLSST.IsrTaskLSST.flatContext | ( | self, | |
exp, | |||
flat, | |||

) |
Context manager that applies and removes flats and darks, if the task is configured to apply them. Parameters ---------- exp : `lsst.afw.image.Exposure` Exposure to process. flat : `lsst.afw.image.Exposure` Flat exposure the same size as ``exp``. dark : `lsst.afw.image.Exposure`, optional Dark exposure the same size as ``exp``. Yields ------ exp : `lsst.afw.image.Exposure` The flat and dark corrected exposure.

lsst.ip.isr.isrTaskLSST.IsrTaskLSST.makeBinnedImages | ( | self, | |

Make visualizeVisit style binned exposures. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to bin. Returns ------- bin1 : `lsst.afw.image.Exposure` Binned exposure using binFactor1. bin2 : `lsst.afw.image.Exposure` Binned exposure using binFactor2.

lsst.ip.isr.isrTaskLSST.IsrTaskLSST.maskDefect | ( | self, | |
exposure, | |||
defectBaseList | |||
) |
Mask defects using mask plane "BAD", in place. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to process. defectBaseList : defect-type List of defects to mask. Can be of type `lsst.ip.isr.Defects` or `list` of `lsst.afw.image.DefectBase`.

level = 'DETECTOR' |
|||
) |
Mask edge pixels with applicable mask plane. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to process. numEdgePixels : `int`, optional Number of edge pixels to mask. maskPlane : `str`, optional Mask plane name to use. level : `str`, optional Level at which to mask edges.
Definition at line 649 of file isrTaskLSST.py.
lsst.ip.isr.isrTaskLSST.IsrTaskLSST.maskNan | ( | self, | |
exposure | |||
) |
Mask NaNs using mask plane "UNMASKEDNAN", in place. Parameters ---------- exposure : `lsst.afw.image.Exposure` Exposure to process. Notes ----- We mask over all non-finite values (NaN, inf), including those that are masked with other bits (because those may or may not be interpolated over later, and we want to remove all NaN/infs). Despite this behaviour, the "UNMASKEDNAN" mask plane is used to preserve the historical name.
