Scientific paper

Table 5 presents the photometry of the individual stars of the M31 remote globular cluster B514. The observations were carried out with the Advanced Camera for Surveys/Wide Field Camera on board of the HST, in the F606W/F814W bands, for total exposure times of 2412s and 2418s respectively. The cluster was placed near the center of the ACS/WFC Chip 2. Data reduction has been performed using the ACS module of DOLPHOT, a point spread function-fitting package specifically devoted to the photometry of HST data, that provides as output the magnitudes and positions of the detected sources, and a number of quality parameters for a suitable sample selection. Table 5 presents all the ACS/WFC Chip 2 stars with valid measurements in both passbands, global quality flag=1, crowding parameter <0.3 and chi-square parameter <1.5. The x,y coordinates, the magnitudes both in the Vegamag and in the Johnson-Cousins systems and the global 'chi' parameter are listed for each of the selected stars.
