A star selector that looks for a cluster of small objects in a size-magnitude plot.
A star selector that looks for a cluster of small objects in a size-magnitude plot.
Like all star selectors, the main method is run
.
See ObjectSizeStarSelectorConfig
ObjectSizeStarSelectorTask has a debug dictionary with the following keys:
For example, put something like:
into your debug.py
file and run your task with the --debug
flag.

Select sources and return them. The input catalog must be contiguous in memory. Parameters: ----------- sourceCat : `lsst.afw.table.SourceCatalog` or `pandas.DataFrame` or `astropy.table.Table` 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` or `pandas.DataFrame` or `astropy.table.Table` 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.

Return a selection of PSF candidates that represent likely stars. A list of PSF candidates may be used by a PSF fitter to construct a PSF. 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 to get the detector to transform to TanPix, and 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.
