doApCorr

Default
True
Field type
bool Field
Run subtask to apply aperture correction

doAstrometry

Default
True
Field type
bool Field
Perform astrometric calibration?

doComputeSummaryStats

Default
True
Field type
bool Field
Run subtask to measure exposure summary statistics?

doDeblend

Default

Default
True
Field type
bool Field

True
Field type
bool Field
Save calibration results?

doWriteExposure

Default
True
Field type

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
