ImsimSchema

The ImSim Schema describes the Science Pipelines outputs for on Imsim simulated full-focal-plane LSSTCam data. It is used in the CI testing of the pipelines.

Tables

name	description	columns
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.	1230
Source	Table to store high signal-to-noise sources. A source is a measurement of Object's properties from a single image that contains its footprint on the sky.	157
ForcedSource	The forced source table contains forced-photometry source measurement on an individual Exposure based on a Multifit shape model derived from a deep detection.	31
DiaObject	The DiaObject table contains descriptions of the astronomical objects detected on one or more difference images.	64
DiaSource	Table to store 'difference image sources', sources detected at SNR >=5 on difference images.	94
ForcedSourceOnDiaObject	This is dia_object_forced_source in the Butler repo.	28
MatchesTruth	Match information for truth_summary sources.	9
MatchesObject	Match information for objectTable_tract sources	6
Visit	Defines a single Visit.	16
VisitDetector	Defines a single detector of a visit.	73
Parent	Descriptions of the parent objects in the deblending hierarchy.	15
