CEFCA announces worldwide open access to the Early Data Release (EDR) of the Javalambre Photometric Local Universe Survey. This EDR consists of 18 J-PLUS pointings at different locations of the sky, observed in the twelve J-PLUS photometric optical bands, overall amounting to 36deg2. We provide access to the J-PLUS catalogues with photometric data in all the twelve bands for more than 400.000 astronomical objects, together with the actual FITS images and proper masks to avoid bright stars and other undesired areas.
