applyDcr

lsst.ip.diffim.applyDcr(maskedImage, dcr, warpCtrl, bbox=None, useInverse=False, splitSubfilters=False)

Shift a masked image.

Parameters:
maskedImage : lsst.afw.image.MaskedImage

The input masked image to shift.

dcr : lsst.afw.geom.Extent2I

Shift calculated with calculateDcr.

warpCtrl : lsst.afw.math.WarpingControl

Configuration settings for warping an image

bbox : lsst.afw.geom.Box2I, optional

Sub-region of the masked image to shift. Shifts the entire image if None (Default).

useInverse : bool, optional

Use the reverse of dcr for the shift. Default: False

splitSubfilters : bool, optional

Calculate DCR for two evenly-spaced wavelengths in each subfilter, instead of at the midpoint. Default: False

Returns:
shiftedImage : lsst.afw.image.maskedImageF

A masked image, with the pixels within the bounding box shifted.
