Cosmological Parameters from pre-Planck CMB Measurements: a 2017 Update
  We present cosmological constraints from the combination of the full mission
9-year WMAP release and small-scale temperature data from the pre-Planck ACT
and SPT generation of instruments. This is an update of the analysis presented
in Calabrese et al. 2013 and highlights the impact on $\Lambda$CDM cosmology of
a 0.06 eV massive neutrino - which was assumed in the Planck analysis but not
in the ACT/SPT analyses - and a Planck-cleaned measurement of the optical depth
to reionization. We show that cosmological constraints are now strong enough
that small differences in assumptions about reionization and neutrino mass give
systematic differences which are clearly detectable in the data. We recommend
that these updated results be used when comparing cosmological constraints from
WMAP, ACT and SPT with other surveys or with current and future full-mission
Planck cosmology. Cosmological parameter chains are publicly available on the
NASA's LAMBDA data archive.
