CLASH Catalog Definitions
Overview
The Cluster Lensing And Supernova survey with Hubble (CLASH) Multi-Cycle Treasury program (PI: Marc Postman) completed its Hubble Space Telescope (HST) multiwavelength obsrvations of 25 massive galaxy clusters in 2013 (Postman et al. 2012 describes the full survey). The full HST dataset and associated catalogs and gravitational lens models are available at MAST. A series or programs with Spitzer have covered all CLASH galaxy clusters with IRAC Channels 1 and 2. Several of the targets include Channels 3 and 4 data.
