Parameter constraints on the ΛCDM+non-minimal neutrino mass model. For this study, we adopt the CCCP prior on the mass bias (see Table 2) and leave the scaling exponent, α, free. The green and red shaded regions show, respectively, the 68 and 95% confidence regions for joint analyses of the cluster counts using the primary CMB, and the primary CMB plus the lensing power spectrum. The solid and dashed black contours add to these two cases constraints from BAO.
