The center of the cluster was covered with a mosaic of F435W, F625W, and F658N band data collected with HST ACS. The outer reaches were covered with a mosaic of U-, B-, V-, and I-band data collected with the 2.2 m ESO/MPI telescope. The final catalog includes ∼1.7 million stars. We identified more than 3200 likely HB stars, the largest sample ever collected in a globular cluster. Description: Photometric data discussed in this investigation belong to two different sets from both space- (HST) and ground-based telescopes. Multiband (U, B, V, I) data have been collected with the mosaic (2x4) CCD camera Wide Field Imager (WFI) available at the 2.2m ESO/MPI telescope (ESO, La Silla). These data have been retrieved from the ESO science archive and include 8 U, 39 B, 51 V, and 26 I pointings.
