The Pantheon SN1e compilation as included with CosmoMC has wrong peculiar velocity corrections carried over in it.

More details have been reported here :

dscolnic/Pantheon#2

More specific to CosmoMC, the data at https://github.com/cmbant/CosmoMC/blob/master/data/Pantheon/lcparam_full_long.txt have exactly the same values for zcmb and zhel, indicating that only the 'corrected' redshifts are being used in the cosmological parameter estimation. I urge caution.
