Retargetable subtasks¶

applyApCorr¶

Default: lsst.meas.base.applyApCorr.ApplyApCorrTask
Field type: ConfigurableField

Subtask to apply aperture corrections

catalogCalculation¶

Default: lsst.meas.base.catalogCalculation.CatalogCalculationTask
Field type: ConfigurableField

Subtask to run catalogCalculation plugins on catalog

measurement¶

Default: lsst.meas.base.forcedMeasurement.ForcedMeasurementTask
Field type: ConfigurableField

subtask to do forced measurement

references¶

Default: lsst.meas.base.references.MultiBandReferencesTask
Field type: ConfigurableField

subtask to retrieve reference source catalog

Configuration fields¶

coaddName¶

Default: 'deep'
Field type: str Field

coadd name: typically one of deep or goodSeeing

connections¶

Data type: lsst.pipe.base.config.Connections
Field type: ConfigField

Configurations describing the connections of the PipelineTask to datatypes

doApCorr¶

Default: True
Field type: bool Field

Run subtask to apply aperture corrections

doApplyExternalPhotoCalib¶

Default: False
Field type: bool Field

Whether to apply external photometric calibration via an lsst.afw.image.PhotoCalib object. Uses the externalPhotoCalibName field to determine which calibration to load.

doApplyExternalSkyWcs¶

Default: False
Field type: bool Field

Whether to apply external astrometric calibration via an lsst.afw.geom.SkyWcs object. Uses externalSkyWcsName field to determine which calibration to load.

doApplySkyCorr¶

Default: False
Field type: bool Field

Apply sky correction?

doApplyUberCal¶

Default: False
Field type: bool Field

Apply meas_mosaic ubercal results to input calexps? Deprecated: Deprecated by DM-23352; use doApplyExternalPhotoCalib and doApplyExternalSkyWcs instead

externalPhotoCalibName¶

Default

'jointcal'

Field type

str ChoiceField (optional)

Choices

'jointcal': Use jointcal_photoCalib
'fgcm': Use fgcm_photoCalib
'fgcm_tract': Use fgcm_tract_photoCalib
None: Field is optional

Type of external PhotoCalib if doApplyExternalPhotoCalib is True. Unused for Gen3 middleware.

externalSkyWcsName¶
