Description

A naive star selector based on second moments. Use with caution.

Task initialisation

Invoking the Task

Like all star selectors, the main method is run.

Configuration parameters

See DiaCatalogSourceSelectorConfig

Debug variables

DiaCatalogSourceSelectorTask has a debug dictionary with the following keys:

display
bool; if True display debug information
displayExposure
bool; if True display exposure
pauseAtEnd
bool; if True wait after displaying everything and wait for user input

For example, put something like:

import lsstDebug
def DebugInfo(name):
di = lsstDebug.getInfo(name) # N.b. lsstDebug.Info(name) would call us recursively
if name.endswith("catalogStarSelector"):
di.display = True
return di
lsstDebug.Info = DebugInfo

into your debug.py file and run your task with the --debug flag.

Select sources for Kernel candidates

@param[in] exposure  the exposure containing the sources
@param[in] sourceCat  catalog of sources that may be stars (an lsst.afw.table.SourceCatalog)
@param[in] matches  a match vector as produced by meas_astrom; required
            (defaults to None to match the StarSelector API and improve error handling)

@return an lsst.pipe.base.Struct containing:
- starCat  a list of sources to be used as kernel candidates
