GlobalInput¶

class lsst.drp.tasks.update_visit_summary.GlobalInput(catalog: ExposureCatalog)¶

Wrapper class for input ExposureCatalog datasets that are not per-tract.

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

best_for_detector(detector_id: int, center: SpherePoint | None = None, bbox: Box2I | None = None) → tuple[int, lsst.afw.table.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.
