ConsolidateVisitSummaryTask#

ConsolidateVisitSummaryTask combines the non-trivial metadata, including the wcs, detector information, psf size and shape, filter, and bounding box corners into one per-visit exposure catalog (dataset visitSummary).

Processing summary#

ConsolidateVisitSummaryTask reads in detector-level processed exposure metadata tables (dataset calexp) for a given visit, combines these data into an exposure catalog, and writes the result out as a visit-level summary catalog (dataset visitSummary). The metadata from each exposure/detector includes:

  • The visitInfo.

  • The wcs.

  • The photoCalib.

  • The physical_filter and band (if available).

  • The psf size, shape, and effective area at the center of the detector.

  • The corners of the bounding box in right ascension/declination.

Other quantities such as PSF, aperture correction map, and transmission curve are not persisted because of storage concerns, and because of their limited utility as summary statistics.

Python API summary#

Butler datasets#

When run through the runQuantum method, ConsolidateVisitSummaryTask obtains datasets from the input Butler data repository and persists outputs to the output Butler data repository.

Input datasets#

calexp

Per-detector, processed exposures with metadata (wcs, psf, etc.)

Output datasets#

visitSummary

Per-visit summary catalog of ccd/visit metadata.

visitSummary_schema

Catalog with no rows with the same schema as visitSummary.
