Please take the MAST Survey.

Cosmic Evolution Survey - COSMOS

COSMOS (P.I. Nicholas Scoville California Institute of Technology, USA/CA) is an HST Treasury Program to survey a 2 square degree equatorial field, centered on RA=10:00:28.6 and DEC=+02:12:21.0 with the ACS in the I band of the VIMOS equatorial field. Parallel observations with WFPC2 and NICMOS were also obtained. Several HST programs are associated with this project: (9822; 9999; 10092; 10337; 10702). The team has also assembled several publically available ancillary datasets including optical spectra, deep XMM and VLA imaging, ground-based optical/IR imaging, UV imaging from GALEX and IR data from SIRTF.

MAST has archived the ACS, WFPC2, NICMOS and GALEX science products from the COSMOS project. They may be downloaded from the lists of data describing the products or via anonymous ftp from archive.stsci.edu. See the table below for the ftp directories.
