Detailed Description

Fit a PSF model at the location of sources in a coadd.

This task is intended to fit only a single PSF model at the
centroid of all of the sources in a single coadd exposure.
Subtasks may choose to filter which sources they fit,
and may output whatever columns they desire in addition to
the minimum of 'id'.

◆ run()

pipeBase.Struct lsst.pipe.tasks.fit_coadd_psf.CoaddPsfFitTask.run	(		self,
		CatalogExposurePsf	catexp )

Fit a PSF model at the location of sources in a coadd.

Parameters
----------
catexp : `typing.List [CatalogExposurePsf]`
    A list of catalog-exposure pairs in a given band.

Returns
-------
retStruct : `lsst.pipe.base.Struct`
    A struct with a cat_output attribute containing the output
    measurement catalog.

Notes
-----
Subtasks may have further requirements; see `CoaddPsfFitSubTask.run`.
