Introduction to the SCP Union2.1 Compilation
The SCP "Union2.1" SN Ia compilation is an update of the "Union2" compilation, now bringing together data for 833 SNe, drawn from 19 datasets. Of these, 580 SNe pass usability cuts. We present new data from the HST Cluster Survey. All SNe were fit using a single lightcurve fitter (SALT2-1) and uniformly analyzed. All analyses and cuts were developed in a blind manner, i.e. with the cosmology hidden. We intend to update the Union2.1 compilation when possible -- please check this page again.

The Union2.1 paper is available here: Suzuki et al. (The Supernova Cosmology Project), accepted for publication, Ap.J., 2011.
Figures and tables from the first Union compilation (Kowalski et al. 2008) and the Union2 compilation (Amanullah et al. 2010) are still available.
