ObjectSizeStarSelectorConfig

class lsst.meas.algorithms.ObjectSizeStarSelectorConfig(*args, **kw)

Bases: BaseSourceSelectorConfig

Attributes Summary

badFlags	List of flags which cause a source to be rejected as bad.
doFluxLimit	Apply flux limit to Psf Candidate selection? (bool, default False)
doSignalToNoiseLimit	Apply signal-to-noise (i.e. flux/fluxErr) limit to Psf Candidate selection? (bool, default True).
fluxMax	Maximum flux value for good Psf Candidates (ignored if == 0).
fluxMin	Minimum flux value for good Psf Candidates.
nSigmaClip	Keep objects within this many sigma of cluster 0's median.
signalToNoiseMax	Maximum signal-to-noise for good Psf Candidates (ignored if == 0).
signalToNoiseMin	Minimum signal-to-noise for good Psf Candidates (value should take into consideration the detection thresholds set for the catalog of interest).
sourceFluxField	Name of field in Source to use for flux measurement.
widthMax	Maximum width to include in histogram.
widthMin	Minimum width to include in histogram.
widthStdAllowed	Standard deviation of width allowed to be interpreted as good stars.

Methods Summary

validate()

Validate the Config, raising an exception if invalid.

badFlags

List of flags which cause a source to be rejected as bad. (List, default ['base_PixelFlags_flag_edge', 'base_PixelFlags_flag_nodata', 'base_PixelFlags_flag_interpolatedCenter', 'base_PixelFlags_flag_saturatedCenter', 'base_PixelFlags_flag_crCenter', 'base_PixelFlags_flag_bad', 'base_PixelFlags_flag_interpolated', 'slot_Centroid_flag'])

doFluxLimit

Apply flux limit to Psf Candidate selection? (bool, default False)

doSignalToNoiseLimit

Apply signal-to-noise (i.e. flux/fluxErr) limit to Psf Candidate selection? (bool, default True)

fluxMax

Maximum flux value for good Psf Candidates (ignored if == 0). (float, default 0.0)

fluxMin

Minimum flux value for good Psf Candidates. (float, default 12500.0)

nSigmaClip

Keep objects within this many sigma of cluster 0’s median. (float, default 2.0)

signalToNoiseMax

Maximum signal-to-noise for good Psf Candidates (ignored if == 0). (float, default 0.0)

signalToNoiseMin

Minimum signal-to-noise for good Psf Candidates (value should take into consideration the detection thresholds set for the catalog of interest). (float, default 50.0)

sourceFluxField

Name of field in Source to use for flux measurement. (str, default 'base_PsfFlux_instFlux')

widthMax

Maximum width to include in histogram. (float, default 10.0)

Methods Documentation

validate()

Validate the Config, raising an exception if invalid.

Raises

lsst.pex.config.FieldValidationError

Raised if verification fails.

Notes

The base class implementation performs type checks on all fields by calling their validate methods.

Complex single-field validation can be defined by deriving new Field types. For convenience, some derived lsst.pex.config.Field-types (ConfigField and ConfigChoiceField) are defined in lsst.pex.config that handle recursing into subconfigs.

Inter-field relationships should only be checked in derived Config classes after calling this method, and base validation is complete.
