PerTractCcdDataIdContainer

class lsst.meas.base.PerTractCcdDataIdContainer(level=None)

Bases: lsst.pipe.base.DataIdContainer

A data ID container which combines raw data IDs with a tract.

Notes

Required because we need to add “tract” to the raw data ID keys (defined as whatever we use for src) when no tract is provided (so that the user is not required to know which tracts are spanned by the raw data ID).

This subclass of DataIdContainer assumes that a calexp is being measured using the detection information, a set of reference catalogs, from the set of coadds which intersect with the calexp. It needs the calexp id (e.g. visit, raft, sensor), but is also uses the tract to decide what set of coadds to use. The references from the tract whose patches intersect with the calexp are used.
