(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, lsst.afw.table.ExposureRecord | None] ¶
Return the exposure record for this detector that is the best match for this detector.
- Parameters:
- detector_id
int
Detector ID; used to find the right row in the catalog or catalogs.
- center
lsst.geom.SpherePoint
orNone
Center of the detector in sky coordinates. If not provided, one will be computed via
compute_center_for_detector_record
.- bbox
lsst.geom.Box2I
, optional Bounding box for the detector in its own pixel coordinates.
- detector_id
- Returns:
- tract_id
int
ID of the tract that supplied this record, or
-1
ifrecord
isNone
or if the input was not per-tract.- record
lsst.afw.table.ExposureRecord
orNone
Best record for this detector, or
None
if there either were no records for this detector or no WCS available to compute a center.
