Detailed Description

Compute the level 20 HtmIndex for the catalog.

Notes
-----
This functor was implemented to satisfy requirements of old APDB interface
which required the ``pixelId`` column in DiaObject with HTM20 index.
The APDB interface had migrated to not need that information, but we keep
this class in case it may be useful for something else.

data,
dropna = False )
inherited

Definition at line 353 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 223 of file functors.py.

◆ _dropna()

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

Definition at line 350 of file functors.py.

◆ _func()

lsst.pipe.tasks.functors.HtmIndex20._func ( self,
df )
protected

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

Definition at line 798 of file functors.py.

◆ _get_columnIndex()

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

Definition at line 299 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 307 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 209 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 189 of file functors.py.

◆ _setLevels()

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

Definition at line 345 of file functors.py.

◆ columns()

◆ 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 365 of file functors.py.

◆ fail()

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

Definition at line 371 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 242 of file functors.py.

◆ name()

◆ noDup()

lsst.pipe.tasks.functors.Functor.noDup ( self)
inherited

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

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