The Cluster Lensing And Supernova survey with Hubble (CLASH) is an HST Multi-Cycle Treasury program (PI: Marc Postman) to survey 25 massive galaxy clusters at 16 wavelengths spanning from the near-UV to the near-IR [Postman et al. (2012)]. The full HST dataset and associated catalogs and gravitational lens models are available at MAST. A series of programs with Spitzer have covered all CLASH galaxy clusters with IRAC Channels 1 and 2 (3.6 and 4.5 micron). Several of the targets include Channels 3 and 4 (5.8 and 8 micron) data.
