Tables B008.dat,B010.dat,B023.dat,B088.dat,B158.dat,B220.dat,B224.dat, B225.dat, B255D.dat,B366.dat,B407.dat present the photometry of the individual stars of 11 M31 globular clusters. The observations were carried out with the ACS on board of the HST, employing the HRC+F606W/F814W filters for B023,B158,B225,and the WFC+ F606W/F814W/F435W for the other clusters. The 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 the pixel positions of the detected sources, and a number of quality parameters for a suitable sample selection. The tables present, for the chip holding the cluster, all the stars with valid measurements in both passbands, global quality flag=1, crowding parameter<0.5 and chi-square parameter<1.5 if V>22.5,and <2.5 if V<22.5. The x,y coordinates, the magnitudes both in the Vegamag and in the Johnson-Cousins systems, the global parameters 'chi', signal to noise, sharpness, and the chip number are listed for each of the selected stars.
