reference object loader for astrometric calibration

astrometry¶

Default: lsst.meas.astrom.astrometry.AstrometryTask
Field type: ConfigurableField

Perform astrometric calibration to refine the WCS

catalogCalculation¶

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

Subtask to run catalogCalculation plugins on catalog

deblend¶

Default: lsst.meas.deblender.deblend.SourceDeblendTask
Field type: ConfigurableField

Split blended sources into their components

detection¶

Default: lsst.meas.algorithms.detection.SourceDetectionTask
Field type: ConfigurableField

Detect sources

evalLocCalib¶

Default: lsst.meas.base.evaluateLocalCalibration.EvaluateLocalCalibrationTask
Field type: ConfigurableField

Task to strip calibrations from an exposure and store their local values in the output source catalog.

insertFakes¶

Default: lsst.pipe.tasks.fakes.BaseFakeSourcesTask
Field type: ConfigurableField

Injection of fake sources for testing purposes (must be retargeted)

measurement¶

Default: lsst.meas.base.sfm.SingleFrameMeasurementTask
Field type: ConfigurableField

Measure sources

photoCal¶

Default: lsst.pipe.tasks.photoCal.PhotoCalTask
Field type: ConfigurableField

Perform photometric calibration

photoRefObjLoader¶

Default: lsst.meas.algorithms.loadIndexedReferenceObjects.LoadIndexedReferenceObjectsTask
Field type: ConfigurableField

reference object loader for photometric calibration

Configuration fields¶

checkUnitsParseStrict¶

Default: 'raise'
Field type: str Field

Strictness of Astropy unit compatibility check, can be ‘raise’, ‘warn’ or ‘silent’

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 correction

doAstrometry¶

Default: True
Field type: bool Field

Perform astrometric calibration?

doDeblend¶

Default: True
Field type: bool Field

Run deblender input exposure

doEvalLocCalibration¶

Default: True
Field type: bool Field

Store calibration products (local wcs and PhotoCalib) in output source catalog.

doInsertFakes¶

Default: False
Field type: bool Field

Run fake sources injection task

doPhotoCal¶

Default: True
Field type: bool Field

Perform phometric calibration?

doWrite¶

Default: True
Field type: bool Field

Save calibration results?

doWriteExposure¶

Default: True
Field type: bool Field

Write the calexp? If fakes have been added then we do not want to write out the calexp as a normal calexp but as a fakes_calexp.

doWriteHeavyFootprintsInSources¶

Default: True
Field type: bool Field

Include HeavyFootprint data in source table? If false then heavy footprints are saved as normal footprints, which saves some space

doWriteMatches¶

Default: True
Field type: bool Field

Write reference matches (ignored if doWrite false)?

doWriteMatchesDenormalized¶

Default: False
Field type: bool Field

Write reference matches in denormalized format? This format uses more disk space, but is more convenient to read. Ignored if doWriteMatches=False or doWrite=False.

icSourceFieldsToCopy¶

Default: ('calib_psf_candidate', 'calib_psf_used', 'calib_psf_reserved')
Field type: str ListField

Fields to copy from the icSource catalog to the output catalog for matching sources Any missing fields will trigger a RuntimeError exception. Ignored if icSourceCat is not provided.

matchRadiusPix¶

Default: 3
Field type: float Field

Match radius for matching icSourceCat objects to sourceCat objects (pixels)

requireAstrometry¶

Default: True
Field type: bool Field

Raise an exception if astrometry fails? Ignored if doAstrometry false.

requirePhotoCal¶

Default: True
Field type: bool Field

Raise an exception if photoCal fails? Ignored if doPhotoCal false.

saveMetadata¶

Default: True
Field type: bool Field

Flag to enable/disable metadata saving for a task, enabled by default.
