Notes. For each filter, we include the Vega-AB conversion factor (if any) used for generating pixel-matched mosaics (see Sect. 3.1), the average PSF FWHM, and the approximate area covered by each survey. The 3σ depths (in AB system) in each filter estimated from the variance of empty, source free 3′′ apertures, and the filter dependent Galactic extinction values, Aband∕E(B − V) are listed.
