◆ _get_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.

Gets the content of each of the column levels for a multilevel table.
Definition at line 209 of file functors.py.
◆ _get_data_columnLevels()
|
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`.

◆ _setLevels()
|
protectedinherited |
Definition at line 345 of file functors.py.
◆ columns()
|
inherited |
Columns required to perform calculation.
Reimplemented from lsst.pipe.tasks.functors.Functor.
Definition at line 2025 of file functors.py.
◆ columns_ref()
|
inherited |
Return columns that are needed from the ref table.
Definition at line 2033 of file functors.py.
◆ compute_ellipse_terms()
|
inherited |
Return terms commonly used for ellipse parameterization conversions.
Parameters
----------
df
The data frame.
sky
Whether to compute the terms in sky coordinates.
If False, XX, YY and XY moments are used instead of
UU, VV and UV.
Returns
-------
xx_p_yy
The sum of the diagonal terms of the covariance.
xx_m_yy
The difference of the diagonal terms of the covariance.
t2
A term similar to the discriminant of the quadratic formula.
Definition at line 2041 of file functors.py.
◆ difference()
|
inherited |
Computes difference between functor called on two different DataFrame/Handle objects.
Definition at line 365 of file functors.py.
◆ fail()
|
inherited |
Definition at line 371 of file functors.py.
◆ get_g1()
|
inherited |
Calculate shear-type ellipticity parameter G1.
Definition at line 2117 of file functors.py.
◆ get_g2()
|
inherited |
Calculate shear-type ellipticity parameter G2. This has the opposite sign as sky_uv in order to maintain consistency with the HSM moments sign convention.

◆ multilevelColumns()
|
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.
