Constructor & Destructor Documentation

def lsst.coadd.chisquared.coadd.Coadd.__init__ (   self,
  bbox,
  wcs,
  badMaskPlanes,
  logName = "coadd.chisquared.Coadd" 
)
Create a chi-squared coadd

Inputs:
@param[in] bbox: bounding box of coadd Exposure with respect to parent (afwGeom.Box2I):
    coadd dimensions = bbox.getDimensions(); xy0 = bbox.getMin()
@param[in] wcs: WCS of coadd exposure (lsst.afw.math.Wcs)
@param[in] badMaskPlanes: mask planes to pay attention to when rejecting masked pixels.
    Specify as a collection of names.
    badMaskPlanes should always include "EDGE".
@param[in] logName: name by which messages are logged

Member Function Documentation

def lsst.coadd.chisquared.coadd.Coadd.addExposure (   self,
  exposure,
  weightFactor = 1.0 
)
Add a an exposure to the coadd; it is assumed to have the same WCS as the coadd

Inputs:
@param[in] 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
@param[in] weightFactor: weight with which to add exposure to coadd

@return
- overlapBBox: region of overlap between exposure and coadd in parent coordinates (afwGeom.Box2I)
- weight: weight with which exposure was added to coadd; weight = weightFactor for this kind of coadd
