Configuration fields¶
connections¶
- Data type
lsst.pipe.base.config.Connections- Field type
ConfigField

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.
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
None- Field 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
None- Field 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).
None- Field 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.
