Coadd¶
-
class
lsst.coadd.chisquared.Coadd(bbox, wcs, badMaskPlanes, logName='coadd.chisquared.Coadd')¶ Bases:
lsst.coadd.utils.coadd.CoaddCreate a chi-squared coadd.
Parameters: - bbox :
lsst.afw.geom.Box2I Bounding box of coadd Exposure with respect to parent: coadd dimensions = bbox.getDimensions(); xy0 = bbox.getMin()
- wcs :
lsst.afw.geom.SkyWcs WCS of coadd exposure
- badMaskPlanes :
listofstr Mask planes to pay attention to when rejecting masked pixels. Specify as a collection of names. badMaskPlanes should always include “EDGE”.
- logName :
str, optional Name by which messages are logged.
Methods Summary
addExposure(exposure[, weightFactor])Add a an exposure to the coadd; it is assumed to have the same WCS as the coadd Methods Documentation

addExposure(exposure, weightFactor=1.0)¶ Add a an exposure to the coadd; it is assumed to have the same WCS as the coadd
Parameters: - exposure :
lsst.afw.image.Exposure Exposure to add to coadd; this must be: - background-subtracted or background-matched to the other images
being coadded
- psf-matched to the desired PSF model (optional)
- warped to match the coadd
- weightFactor :
float weight with which to add exposure to coadd
Returns: - overlapBBox :
lsst.afw.geom.Box2I Region of overlap between
exposureand coadd in parent coordinates.- weight :
float Weight with which
exposurewas added to coadd; weight = weightFactor for this kind of coadd.
