VIRAC: The VVV Infrared Astrometric Catalogue
We present VIRAC version 1, a near-infrared proper motion and parallax catalogue of the VISTA VVV survey for 312,587,642 unique sources averaged across all overlapping pawprint and tile images covering 560 deg\(^2\) of the bulge of the Milky Way and southern disk. The catalogue includes 119 million...

Zusammenfassung: | We present VIRAC version 1, a near-infrared proper motion and parallax catalogue of the VISTA VVV survey for 312,587,642 unique sources averaged across all overlapping pawprint and tile images covering 560 deg\(^2\) of the bulge of the Milky Way and southern disk. The catalogue includes 119 million high quality proper motion measurements, of which 47 million have statistical uncertainties below 1 mas yr\(^{-1}\). In the 11\( |
