ConsolidateVisitSummaryTask¶
ConsolidateVisitSummaryTask
combines the non-trivial metadata, including the wcs, detector id, psf size and shape, filter, and bounding box corners into one per-visit exposure catalog (dataset visitSummary
).
ConsolidateVisitSummaryTask
is available as a command-line task, consolidateVisitSummary.py.
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
andband
(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 detector, PSF, aperture correction map, and transmission curve are not persisted because of storage concerns, and because of their limited utility as summary statistics.
consolidateVisitSummary.py command-line interface¶
consolidateVisitSummary.py REPOPATH [@file [@file2 ...]] [--output OUTPUTREPO | --rerun RERUN] [--id] [other options]
Key arguments:
- REPOPATH¶
The input Butler repository’s URI or file path.
Key options:
- --id¶
The data IDs to process.

Butler datasets¶
When run as the consolidateVisitSummary.py
command-line task, or directly through the runDataRef
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
.
