HyperSuprimeCam

The HyperSuprimeCam (HSC) Schema describes the outputs of the latest data release production pipelines for HyperSuprimeCam. This schema is used by ci_hsc, which verifies the schema of the pipeline output files.


Object

The Object table contains descriptions of the multi-epoch static astronomical objects, in particular their astrophysical properties as derived from analysis of the Sources that are associated with them. Note that fast moving objects are kept in the MovingObject tables. Note that less-frequently used columns are stored in a separate table called Object_Extra.
