Description

A star selector whose algorithm is not yet documented

Task initialisation

Invoking the Task

Like all star selectors, the main method is run.

Configuration parameters

See PsfexStarSelectorConfig

Debug variables

PsfexStarSelectorTask has a debug dictionary with the following keys:

display: bool; if True display debug information
displayExposure: bool; if True display the exposure and spatial cells
plotFwhmHistogram: bool; if True plot histogram of FWHM
plotFlags: bool: if True plot the sources coloured by their flags
plotRejection: bool; if True plot why sources are rejected

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("objectSizeStarSelector"):
        di.display = True
        di.displayExposure = True
        di.plotFwhmHistogram = True
    return di
lsstDebug.Info = DebugInfo

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

Select stars from source catalog.

Parameters

[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

Returns

a Struct containing:

starCat a subset of sourceCat containing the selected stars
