Description

A “Solar System object” is a moving object for which groupings of difference image detections (DIASources) have been linked together.

The SS object table contains the unique SSObjectId identifier, number of observations, and the date of the discovery submission (if a new discovery) for each solar system object detected with signal-to-noise ratio >5.

The DP1 version of the SS object table is very minimal, with only 3 columns. Future versions of this table will include, for example, the best fit absolute magnitude and slope (G and H) parameters per band and associated statistics.

Processing

The SS object catalog is the result of Solar System processing (SSP).
