Traditional photometric catalogue matching will fail for Rubin Obs. LSST, as typical 2" error circles will contain up to 10 random objects. Bayesian cross-matching techniques which include the astrometric uncertainty of the observations ultimately assume that the Astrometric Uncertainty Function of the sources is Gaussian, which will not apply to LSST. The extreme source densities and significant number of objects with no known proper motion mean that systematic effects, not noise-baseddoi:10.5281/zenodo.4562155 fatcat:2k5wkl4dxfbebde74lalhmbwaa
