PossiblyMultipleInput

class lsst.drp.tasks.update_visit_summary.PossiblyMultipleInput

Bases: ABC

A helper ABC for handling input ExposureCatalog datasets that may be multiple (one per tract/visit combination) or unique/global (one per visit).

Methods Summary

best_for_detector(detector_id[, center, bbox])

Return the exposure record for this detector that is the best match for this detector.

Methods Documentation

abstract best_for_detector(detector_id: int, center: SpherePoint | None = None, bbox: Box2I | None = None) → tuple[int, ExposureRecord | None]

Return the exposure record for this detector that is the best match for this detector.

Parameters

detector_idint

Detector ID; used to find the right row in the catalog or catalogs.

centerlsst.geom.SpherePoint or None

Center of the detector in sky coordinates. If not provided, one will be computed via compute_center_for_detector_record.

bboxlsst.geom.Box2I, optional

Bounding box for the detector in its own pixel coordinates.

Returns

tract_idint

ID of the tract that supplied this record, or -1 if record is None or if the input was not per-tract.

recordlsst.afw.table.ExposureRecord or None

Best record for this detector, or None if there either were no records for this detector or no WCS available to compute a center.
