MergeMeasurementsConfig

class lsst.pipe.tasks.mergeMeasurements.MergeMeasurementsConfig(*args, **kw)

Bases: PipelineTaskConfig

Configuration parameters for the MergeMeasurementsTask.

Attributes Summary

coaddName	Name of coadd (str, default 'deep')
connections	Field which refers to a dynamically added configuration class which is based on a PipelineTaskConnections class.
flags	Require that these flags, if available, are not set (List, default ['base_PixelFlags_flag_interpolatedCenter', 'base_PsfFlux_flag', 'ext_photometryKron_KronFlux_flag', 'modelfit_CModel_flag'])
minSN	If the S/N from the priority band is below this value (and the S/N is larger than minSNDiff compared to the priority band), use the band with the largest S/N as the reference band.
minSNDiff	If the difference in S/N between another band and the priority band is larger than this value (and the S/N in the priority band is less than minSN) use the band with the largest S/N as the reference band (float, default 3.0)
priorityList	Priority-ordered list of filter bands for the merge.
pseudoFilterList	Names of filters which may have no associated detection (N.b.
saveLogOutput	Flag to enable/disable saving of log output for a task, enabled by default.
snName	Name of flux measurement for calculating the S/N when choosing the reference band.

Methods Summary

validate()

Validate the Config, raising an exception if invalid.

Attributes Documentation

coaddName

Name of coadd (str, default 'deep')

connections: pexConfig.ConfigField

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

flags

Require that these flags, if available, are not set (List, default ['base_PixelFlags_flag_interpolatedCenter', 'base_PsfFlux_flag', 'ext_photometryKron_KronFlux_flag', 'modelfit_CModel_flag'])

minSN

If the S/N from the priority band is below this value (and the S/N is larger than minSNDiff compared to the priority band), use the band with the largest S/N as the reference band. (float, default 10.0)

minSNDiff

If the difference in S/N between another band and the priority band is larger than this value (and the S/N in the priority band is less than minSN) use the band with the largest S/N as the reference band (float, default 3.0)

priorityList

Priority-ordered list of filter bands for the merge. (List, default [])

pseudoFilterList

Names of filters which may have no associated detection (N.b. should include MergeDetectionsConfig.skyFilterName) (List, default ['sky'])

saveLogOutput

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

snName

Name of flux measurement for calculating the S/N when choosing the reference band. (str, default 'base_PsfFlux')

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.
