Retargetable subtasks¶
applyApCorr¶
- Default
- Field type
Subtask to apply aperture corrections
catalogCalculation¶
Subtask to run catalogCalculation plugins on catalog
match¶
- Default
lsst.meas.astrom.directMatch.DirectMatchTask
- Field type
Matching to reference catalog
measurement¶
- Default
- Field type
Source measurement
propagateFlags¶
Propagate source flags to coadd
setPrimaryFlags¶
- Default
- Field type
Set flags for primary tract/patch
Configuration fields¶
checkUnitsParseStrict¶
Strictness of Astropy unit compatibility check, can be ‘raise’, ‘warn’ or ‘silent’
coaddName¶
Name of coadd
connections¶
- Data type
lsst.pipe.base.config.Connections
- Field type
Configurations describing the connections of the PipelineTask to datatypes
doAddFootprints¶
Whether or not to add footprints to the input catalog from scarlet models. This should be true whenever using the multi-band deblender, otherwise this should be False.
doApCorr¶
Apply aperture corrections
doConserveFlux¶
Whether to use the deblender models as templates to re-distribute the flux from the ‘exposure’ (True), or to perform measurements on the deblender model footprints.
doMatchSources¶
Match sources to reference catalog?
doPropagateFlags¶
Whether to match sources to CCD catalogs to propagate flags (to e.g. identify PSF stars)
doRunCatalogCalculation¶
Run catalogCalculation task
doStripFootprints¶
Whether to strip footprints from the output catalog before saving to disk. This is usually done when using scarlet models to save disk space.
doWriteMatchesDenormalized¶
Write reference matches in denormalized format? This format uses more disk space, but is more convenient to read.
hasFakes¶
Should be set to True if fake sources have been inserted into the input data.
inputCatalog¶
- Default
'deblendedCatalog'
- Field type
str
ChoiceField
(optional)- Choices
'deblendedCatalog'
Output catalog from ScarletDeblendTask
'deblendedFlux'
Output catalog from SourceDeblendTask
'mergeDet'
The merged detections before deblending.
None
Field is optional
The name of the input catalog.
psfCache¶
Size of psfCache
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.
