Parameters
----------

    `~lsst.daf.butler.DeferredDatasetHandle` or
    `~lsst.pipe.base.InMemoryDatasetHandle`.
columnIndex (optional): pandas `~pandas.Index` object
    If not passed, then it is read from the
    `~lsst.daf.butler.DeferredDatasetHandle`
    for `~lsst.pipe.base.InMemoryDatasetHandle`.

		dn,
		dnErr,
		fluxMag0,
		fluxMag0Err )

◆ dn2mag()

lsst.pipe.tasks.functors.Photometry.dn2mag	(	self,
		dn,
		fluxMag0 )

◆ multilevelColumns()

lsst.pipe.tasks.functors.Functor.multilevelColumns	(	self,
		data,
		columnIndex = None,
		returnTuple = False )

inherited

Returns columns needed by functor from multilevel dataset.

To access tables with multilevel column structure, the
`~lsst.daf.butler.DeferredDatasetHandle` or
`~lsst.pipe.base.InMemoryDatasetHandle` needs to be passed
either a list of tuples or a dictionary.

Parameters
----------
data : various
    The data as either `~lsst.daf.butler.DeferredDatasetHandle`, or
    `~lsst.pipe.base.InMemoryDatasetHandle`.
columnIndex (optional): pandas `~pandas.Index` object
    Either passed or read in from
    `~lsst.daf.butler.DeferredDatasetHandle`.
`returnTuple` : `bool`
    If true, then return a list of tuples rather than the column
    dictionary specification.
    This is set to `True` by `CompositeFunctor` in order to be able to
    combine columns from the various component functors.

Reimplemented in lsst.pipe.tasks.functors.Color, and lsst.pipe.tasks.functors.CompositeFunctor.

Definition at line 242 of file functors.py.
