"""Create 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 : `list` of `str` 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. """

"""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 ``exposure`` and coadd in parent coordinates. weight : `float` Weight with which ``exposure`` was added to coadd; weight = weightFactor for this kind of coadd. """
