Description

A “DIA object” is an astrophysical transient or variable object at a static sky coordinate. The DIA object table is created by associating DIA sources within a 1 arcsecond radius. This table contains derived per-filter parameters (e.g., minimum/maximum flux, linear fit results).

Processing

The DIA object catalog is the result of Difference image analysis (DIA).
