Left: sky view of the VISTA footprint (VHS in grey and VIKING in red) compared to the VHS-ESO DR4 (blue). Right: histograms of RA and Dec for the VISTA Surveys that we used for this VEXAS-DR1. The total number of objects in the catalogue is shown above each histogram. Bottom: distribution of Ks, J, H, and Y magnitudes of the input VISTA table, with number of objects within the magnitude ranges of Eq. (1) given in the top left corner of each panel. The VSH has a very broad coverage in J and Ks, but only observed H and Y in a few fields.
