Recovered CMB lensing mass M_CMBlens (divided by the SZ mass M_SZ) as a function of SZ mass for the Planck + SPT-SZ combined analysis. Black dots are individual measurements. The red dots are the weighted means of the five mass bins, spaced logarithmically. The dotted (resp. dashed) blue line is the zero (resp. unity) level. The green stripe is the weighted mean within the error 〈M_CMBlens/M_SZ〉 = 0.919 ± 0.190 (without correcting for the kSZ effect).
