A star selector based on second moments.
A star selector based on second moments.
Like all star selectors, the main method is run
.

SecondMomentStarSelectorTask has a debug dictionary with the following keys:
display = lsstDebug.Info(name).display displayExposure = lsstDebug.Info(name).displayExposure pauseAtEnd = lsstDebug.Info(name).pauseAtEnd
For example, put something like:
into your debug.py
file and run your task with the --debug
flag.

Return a list of PSF candidates that represent likely stars.
A list of PSF candidates may be used by a PSF fitter to construct a PSF.
[in] | exposure | the exposure containing the sources |
[in] | sourceCat | catalog of sources that may be stars (an lsst.afw.table.SourceCatalog) |
[in] | matches | astrometric matches; ignored by this star selector |
