Detailed Description

Select sources that are useful for astrometry.

Good astrometry sources have high signal/noise, are non-blended, and
did not have certain "bad" flags set during source extraction. They need not
be PSF sources, just have reliable centroids.

Constructor & Destructor Documentation

◆ init()

def lsst.meas.algorithms.astrometrySourceSelector.AstrometrySourceSelectorTask.__init__	(	self,
		args,
		kwargs
	)

Definition at line 72 of file astrometrySourceSelector.py.

Member Function Documentation

◆ run()

def lsst.meas.algorithms.sourceSelector.BaseSourceSelectorTask.run	(	self,
		sourceCat,
		sourceSelectedField = `None`,
		matches = `None`,
		exposure = `None`
	)

inherited

Select sources and return them.

The input catalog must be contiguous in memory.

Parameters:
-----------
sourceCat : `lsst.afw.table.SourceCatalog`
    Catalog of sources to select from.
sourceSelectedField : `str` or None
    Name of flag field in sourceCat to set for selected sources.
    If set, will modify sourceCat in-place.
matches : `list` of `lsst.afw.table.ReferenceMatch` or None
    List of matches to use for source selection.
    If usesMatches is set in source selector this field is required.
    If not, it is ignored.
exposure : `lsst.afw.image.Exposure` or None
    The exposure the catalog was built from; used for debug display.

Return
------
struct : `lsst.pipe.base.Struct`
    The struct contains the following data:

    - sourceCat : `lsst.afw.table.SourceCatalog`
The catalog of sources that were selected.
(may not be memory-contiguous)
    - selected : `numpy.ndarray` of `bool``
Boolean array of sources that were selected, same length as
sourceCat.

Raises
------
RuntimeError
    Raised if ``sourceCat`` is not contiguous.

◆ selectSources()

def lsst.meas.algorithms.astrometrySourceSelector.AstrometrySourceSelectorTask.selectSources	(	self,
		sourceCat,
		matches = `None`,
		exposure = `None`
	)

Return a selection of sources that are useful for astrometry.

Parameters:
-----------
sourceCat : `lsst.afw.table.SourceCatalog`
    Catalog of sources to select from.
    This catalog must be contiguous in memory.
matches : `list` of `lsst.afw.table.ReferenceMatch` or None
    Ignored in this SourceSelector.
exposure : `lsst.afw.image.Exposure` or None
    The exposure the catalog was built from; used for debug display.

Return
------
struct : `lsst.pipe.base.Struct`
    The struct contains the following data:

    - selected : `array` of `bool``
Boolean array of sources that were selected, same length as
sourceCat.
