  cd11,
  cd12,
  cd21,
  cd22 
)
inherited
Compute the distance on the sphere from x2, y1 to x1, y1.

Parameters
----------
x1 : `pandas.Series`
    X pixel coordinate.
y1 : `pandas.Series`
    Y pixel coordinate.
x2 : `pandas.Series`
    X pixel coordinate.
y2 : `pandas.Series`
    Y pixel coordinate.
cd11 : `pandas.Series`
    [1, 1] element of the local Wcs affine transform.
cd11 : `pandas.Series`
    [1, 1] element of the local Wcs affine transform.

    [1, 2] element of the local Wcs affine transform.
cd21 : `pandas.Series`
    [2, 1] element of the local Wcs affine transform.
cd22 : `pandas.Series`
    [2, 2] element of the local Wcs affine transform.

Returns
-------
Distance : `pandas.Series`
    Arcseconds per pixel at the location of the local WC

◆ multilevelColumns()

def 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 `MultilevelParquetTable`
or `DeferredDatasetHandle` need to be passed either a list of tuples or a
dictionary.

Parameters
----------
data : `MultilevelParquetTable` or `DeferredDatasetHandle`

columnIndex (optional): pandas `Index` object
    either passed or read in from `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.
