Function Documentation

◆ checkPatchList()

def lsst.ip.diffim.getTemplate.checkPatchList	(	self,
		patchList
	)

Check that all of the DcrModel subfilters are present for each patch.

Parameters
----------
patchList : `dict`
    Dict of the patches containing valid data for each tract

Raises
------
RuntimeError
    If the number of exposures found for a patch does not match the number of subfilters.

Definition at line 823 of file getTemplate.py.

◆ getDcrModel()

def lsst.ip.diffim.getTemplate.getDcrModel	(	self,
		patchList,
		coaddRefs,
		visitInfo
	)

Build DCR-matched coadds from a list of exposure references.

Parameters
----------
patchList : `dict`
    Dict of the patches containing valid data for each tract
coaddRefs : `list` of elements of type
            `lsst.daf.butler.DeferredDatasetHandle` of
            `lsst.afw.image.Exposure`
    Data references to DcrModels that overlap the detector.
visitInfo : `lsst.afw.image.VisitInfo`
    Metadata for the science image.

Returns
-------
`list` of elements of type `lsst.afw.image.Exposure`
        Coadd exposures that overlap the detector.

Definition at line 842 of file getTemplate.py.

◆ run()

def lsst.ip.diffim.getTemplate.run	(		self,
			coaddExposures,
			bbox,
			wcs,
			dataIds,
		**	kwargs
	)

Warp coadds from multiple tracts to form a template for image diff.

Where the tracts overlap, the resulting template image is averaged.
The PSF on the template is created by combining the CoaddPsf on each
template image into a meta-CoaddPsf.

Parameters
----------
coaddExposures : `list` of `lsst.afw.image.Exposure`
    Coadds to be mosaicked
bbox : `lsst.geom.Box2I`
    Template Bounding box of the detector geometry onto which to
    resample the coaddExposures
wcs : `lsst.afw.geom.SkyWcs`
    Template WCS onto which to resample the coaddExposures
dataIds : `list` of `lsst.daf.butler.DataCoordinate`
    Record of the tract and patch of each coaddExposure.
**kwargs
    Any additional keyword parameters.

Returns
-------
result : `lsst.pipe.base.Struct` containing
    - ``outputExposure`` : a template coadd exposure assembled out of patches
