Detailed Description

Functor to calculate the SDSS trace radius size for sources.

The SDSS trace radius size is a measure of size equal to the square root of
half of the trace of the second moments tensor measured with the
SdssShapeAlgorithm plugin.
This has units of pixels.

Member Function Documentation

◆ call()

lsst.pipe.tasks.functors.Functor.__call__	(	self,
		data,
		dropna = False )

inherited

Definition at line 355 of file functors.py.

◆ _colsFromDict()

lsst.pipe.tasks.functors.Functor._colsFromDict	(	self,
		colDict,
		columnIndex = None )

protectedinherited

Converts dictionary column specficiation to a list of columns.

Definition at line 225 of file functors.py.

◆ _dropna()

lsst.pipe.tasks.functors.Functor._dropna	(		self,
			vals )

protectedinherited

Definition at line 352 of file functors.py.

◆ _func()

lsst.pipe.tasks.functors.SdssTraceSize._func	(		self,
			df )

protected

Reimplemented from lsst.pipe.tasks.functors.Functor.

Definition at line 1060 of file functors.py.

◆ _get_columnIndex()

lsst.pipe.tasks.functors.Functor._get_columnIndex	(		self,
			data )

protectedinherited

Return columnIndex.

Definition at line 301 of file functors.py.

◆ _get_data()

lsst.pipe.tasks.functors.Functor._get_data	(		self,
			data )

protectedinherited

Retrieve DataFrame necessary for calculation.

The data argument can be a `~pandas.DataFrame`, a
`~lsst.daf.butler.DeferredDatasetHandle`, or
an `~lsst.pipe.base.InMemoryDatasetHandle`.

Returns a DataFrame upon which `self._func` can act.

Definition at line 309 of file functors.py.

◆ _get_data_columnLevelNames()

lsst.pipe.tasks.functors.Functor._get_data_columnLevelNames	(	self,
		data,
		columnIndex = None )

protectedinherited

Gets the content of each of the column levels for a multilevel
table.

Definition at line 211 of file functors.py.

◆ _get_data_columnLevels()

lsst.pipe.tasks.functors.Functor._get_data_columnLevels	(	self,
		data,
		columnIndex = None )

protectedinherited

Gets the names of the column index levels.

This should only be called in the context of a multilevel table.

Parameters
----------
data : various
    The data to be read, can be a
    `~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`.

Definition at line 191 of file functors.py.

◆ _setLevels()

lsst.pipe.tasks.functors.Functor._setLevels	(		self,
			df )

protectedinherited

Definition at line 347 of file functors.py.

◆ columns()

lsst.pipe.tasks.functors.Functor.columns ( self )

inherited

Columns required to perform calculation.

Definition at line 185 of file functors.py.

◆ difference()

lsst.pipe.tasks.functors.Functor.difference	(		self,
			data1,
			data2,
		**	kwargs )

inherited

Computes difference between functor called on two different
DataFrame/Handle objects.

Definition at line 367 of file functors.py.

◆ fail()

lsst.pipe.tasks.functors.Functor.fail	(		self,
			df )

inherited

Definition at line 373 of file functors.py.

◆ 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 244 of file functors.py.

◆ name()

lsst.pipe.tasks.functors.Functor.name ( self )

inherited

inherited

Definition at line 177 of file functors.py.

◆ shortname()

lsst.pipe.tasks.functors.Functor.shortname ( self )

inherited

Short name of functor (suitable for column name/dict key).

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

Definition at line 382 of file functors.py.
