Summary of mass scale priors.
|Prior name||Quantity||Value and Gaussian errors|
|Weighing the Giants (WtG)||1−b||0.688 ± 0.072|
|Canadian Cluster Comparison|
|Project (CCCP)||1−b||0.780 ± 0.092|
|CMB lensing (CMBlens)||1 / (1−b)||0.99 ± 0.19|
|Baseline 2013||1−b||0.8 [− 0.1, + 0.2]|
Notes. For CCCP, we use the value determined for Planck clusters at S/N> 7 (Hoekstra et al. 2015, left column of p. 706) and we add in quadrature the statistical (0.07) and systematic (0.06) uncertainties. CMB lensing directly measures 1 / (1−b), which we implement in our analysis; purely for reference, this constraint translates approximately to . The last line shows the 2013 baseline – a reference model defined by 1−b = 0.8 with a flat prior in the [0.7, 1] range.
