Together with extensive ground-based spectroscopy taken from the literature, augmented with over a hundred newly determined redshifts, this unique data set enables us to examine environmental influences on the properties of cluster members from the inner core to well beyond the virial radius (∼1.7Mpc). We catalog photometric measures for 22000 objects to I≳25 and assign morphological types for 2181 to I=22.5, of which 195 are spectroscopically confirmed cluster members. File Summary:

Note (1): All magnitudes are in the Vega system and corrected for galactic extinction, adopting E(B-V)=0.057 (Schlegel et al., 1998ApJ...500..525S). The value -999.999 indicates numerical problems in computing the quantity.
Global notes: Note (G1): Objects identified as [TEK2003] NN-N-NNN in Simbad
