GALACTICNUCLEUS DR1 color (from bands Ks, H, J) HiPS

The GALACTICNUCLEUS (GNS) survey is a single-epoch catalog of the Galactic Centre in the near-infrared bands JHKs. The observations were optimised for the Galactic Center: high angular resolution (0.2") to overcome extreme crowding and high dynamic range to minimise saturation issues. The data were acquired with the HAWK-I intrument at the ESO VLT unit telescope 4. The catalogue covers an area of ~0.3 square degrees (~6000 square pc) distributed across seven regions that correspond to the nuclear stellar disc (NSD), the inner Galactic Bulge and the transition region between them.
