# LSSTCam-imSim Schema

The ImSim Schema describes the Science Pipelines outputs for on Imsim simulated full-focal-plane LSSTCam data. The data preview dataset schemas (e.g. DP01, DP02) are derived from this one, but are fixed at the time of that data release.

## 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.
