Abstract:
We present a study of the density profile of the remote M 31 globular
cluster B514, obtained from HST/ACS observations.
Description:
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.
