This figure demonstrates the impact of each combination of data sets on the constraints on ∑
m
ν and
N
eff. The shaded contours are the 68% and 95% confidence intervals for the following data combinations: SPT+
WMAP 7 (CMB; red), CMB+
H
0 (green), CMB+
H
0 +BAO (blue), CMB+
H
0 +BAO+
(purple). The combined data are in >2σ tension with the ΛCDM assumption of three massless neutrino species.
