资源简介：
The HST ACS Coma Cluster Treasury Survey is a deep, two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656, HST Proposal 10861). While HST data were obtained with both the ACS and NICMOS instruments, only the ACS data are included in this release. The survey was designed to cover an area of 740 square arcmin in regions of different density of both galaxies and intergalactic medium within the cluster. The ACS failure of January 27th 2007 left the survey 28% complete, with 21 ACS pointings (230 square arcmin) completed, and partial data for a further 4 pointings (44 square arcmin).
