WMAP Chain Updates 7.2
The "WMAP 7.1" chains that were released on 11/19/2010 had a small bug that affected the weight attached to each point in the chain. This has been corrected and the WMAP 7.1 chains have been replaced with WMAP 7.2 chains. The main effect of the bug was to introduce some artificial roll-off in the likelihood of the SZ amplitude parameter (which is largely unconstrained by WMAP). There was also some small effect on parameters like Ων2, which also has a sharp cutoff (it has to be greater than zero).
