Description This catalog provides a comprehensive census of the stellar populations in the inner ~300 sqdeg of the Galaxy. It is based on observations obtained with VISTA as part of the ESO public survey VVV. The measurements were obtained by performing PSF-fitting photometry of multi-epoch J and Ks images.
