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. Spitzer mosaics, catalogs, and PSF images are available at IRSA.
The December 2014 update added the cluster CLJ1226.
