Abstract:
We describe a new wide-field Hubble Space Telescope survey of the
galaxy cluster Cl 0024+16 (z∼0.4) consisting of a sparsely sampled
mosaic of 39 Wide Field Planetary Camera 2 images that extends to a
cluster radius of ∼5Mpc. 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.

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 1998ApJ...500..525S). The value -999.999 indicates numerical problems
in computing the quantity.
