ProcessBrightStarsConfig

class lsst.pipe.tasks.processBrightStars.ProcessBrightStarsConfig(*args, **kw)

Bases: PipelineTaskConfig

Configuration parameters for ProcessBrightStarsTask.

Attributes Summary

annularFluxRadii	Inner and outer radii of the annulus used to compute AnnularFlux for normalization, in pixels.
annularFluxStatistic	Type of statistic to use to compute annular flux.
badMaskPlanes	Mask planes that identify pixels to not include in the computation of the annular flux.
connections	Field which refers to a dynamically added configuration class which is based on a PipelineTaskConnections class.
discardNanFluxStars	Should stars with NaN annular flux be discarded? (bool, default False)
doApplySkyCorr	Apply full focal plane sky correction before extracting stars? (bool, default True)
doApplyTransform	Apply transform to bright star stamps to correct for optical distortions? (bool, default True)
doRemoveDetected	Whether secondary DETECTION footprints (i.e., footprints of objects other than the central primary object) should be changed to BAD.
magLimit	Magnitude limit, in Gaia G; all stars brighter than this value will be processed.
minValidAnnulusFraction	Minumum number of valid pixels that must fall within the annulus for the bright star to be saved for subsequent generation of a PSF.
modelStampBuffer	'Buffer' factor to be applied to determine the size of the stamp the processed stars will be saved in.
numIter	Number of iterations of outlier rejection; ignored if annularFluxStatistic != 'MEANCLIP'.
numSigmaClip	Sigma for outlier rejection; ignored if annularFluxStatistic != 'MEANCLIP'.
refObjLoader	Reference object loader for astrometric calibration.
saveLogOutput	Flag to enable/disable saving of log output for a task, enabled by default.
stampSize	Size of the stamps to be extracted, in pixels.
warpingKernelName	Warping kernel.

Attributes Documentation

annularFluxRadii

Inner and outer radii of the annulus used to compute AnnularFlux for normalization, in pixels. (List, default (70, 80))

annularFluxStatistic

Type of statistic to use to compute annular flux. (str, default 'MEANCLIP')

Allowed values:

'MEAN'

mean

'MEDIAN'

median

'MEANCLIP'

clipped mean

'None'

Field is optional

badMaskPlanes

Mask planes that identify pixels to not include in the computation of the annular flux. (List, default ('BAD', 'CR', 'CROSSTALK', 'EDGE', 'NO_DATA', 'SAT', 'SUSPECT', 'UNMASKEDNAN'))

connections: pexConfig.ConfigField

Field which refers to a dynamically added configuration class which is based on a PipelineTaskConnections class.

discardNanFluxStars

Should stars with NaN annular flux be discarded? (bool, default False)

doApplySkyCorr

Apply full focal plane sky correction before extracting stars? (bool, default True)

doApplyTransform

Apply transform to bright star stamps to correct for optical distortions? (bool, default True)

doRemoveDetected

Whether secondary DETECTION footprints (i.e., footprints of objects other than the central primary object) should be changed to BAD. (bool, default True)

magLimit

saveLogOutput

Flag to enable/disable saving of log output for a task, enabled by default. (bool, default True)

stampSize

Size of the stamps to be extracted, in pixels. (List, default (250, 250))

warpingKernelName

Warping kernel. (str, default 'lanczos5')
