Retargetable subtasks¶
applyApCorr¶
- Default
- Field type
Subtask to apply aperture corrections
catalogCalculation¶
Subtask to run catalogCalculation plugins on catalog
measurement¶
- Default
- Field type
subtask to do forced measurement
references¶
- Default
- Field type
subtask to retrieve reference source catalog
Configuration fields¶
coaddName¶
coadd name: typically one of deep or goodSeeing
connections¶
- Data type
lsst.pipe.base.config.Connections- Field type
Configurations describing the connections of the PipelineTask to datatypes
doApCorr¶
Run subtask to apply aperture corrections
doApplyExternalPhotoCalib¶
Whether to apply external photometric calibration via an lsst.afw.image.PhotoCalib object. Uses the externalPhotoCalibName field to determine which calibration to load.
doApplyExternalSkyWcs¶
Whether to apply external astrometric calibration via an lsst.afw.geom.SkyWcs object. Uses externalSkyWcsName field to determine which calibration to load.
doApplyFinalizedPsf¶
Whether to apply finalized psf models and aperture correction map.
doApplySkyCorr¶
Apply sky correction?
doApplyUberCal¶
Apply meas_mosaic ubercal results to input calexps? Deprecated: Deprecated by DM-23352; use doApplyExternalPhotoCalib and doApplyExternalSkyWcs instead
externalPhotoCalibName¶
- Default
'jointcal'- Field type
strChoiceField(optional)- Choices
'jointcal'Use jointcal_photoCalib
'fgcm'Use fgcm_photoCalib
'fgcm_tract'Use fgcm_tract_photoCalib
NoneField is optional
Type of external PhotoCalib if doApplyExternalPhotoCalib is True. Unused for Gen3 middleware.
externalSkyWcsName¶
- Default
'jointcal'- Field type
strChoiceField(optional)- Choices
'jointcal'Use jointcal_wcs
NoneField is optional
Type of external SkyWcs if doApplyExternalSkyWcs is True. Unused for Gen3 middleware.
footprintSource¶
- Default
'transformed'- Field type
strChoiceField(optional)- Choices
'transformed'Transform footprints from the reference catalog (downgrades HeavyFootprints).
'psf'Use the scaled shape of the PSF at the position of each source (does not generate HeavyFootprints).
NoneField is optional
Where to obtain footprints to install in the measurement catalog, prior to measurement.
includePhotoCalibVar¶
Add photometric calibration variance to warp variance plane?
psfFootprintScaling¶
Scaling factor to apply to the PSF shape when footprintSource=’psf’ (ignored otherwise).
saveLogOutput¶
Flag to enable/disable saving of log output for a task, enabled by default.
saveMetadata¶
Flag to enable/disable metadata saving for a task, enabled by default.
useGlobalExternalPhotoCalib¶
When using doApplyExternalPhotoCalib, use ‘global’ calibrations that are not run per-tract. When False, use per-tract photometric calibration files.
useGlobalExternalSkyWcs¶
When using doApplyExternalSkyWcs, use ‘global’ calibrations that are not run per-tract. When False, use per-tract wcs files.
