Mass-Redshift Distribution of the SPT-SZ, the SPTpol 100d, the SPT-ECS and the Planck cosmological cluster samples We compare the 2500 deg2 SPT-SZ cluster catalog, the SPTpol 100d, the SPT-ECS cluster sample and the new evaluation of Planck cluster masses. Plotted are the estimated mass versus redshift for the 539 optically-confirmed clusters from the SPT-SZ catalog, 79 clusters from the SPTpol 100d sample, 448 SPT-ECS clusters, and the 439 clusters from the Planck cosmological sample (the sample being defined in Planck 2015, XXVII. The second Planck catalogue of Sunyaev-Zeldovich sources). As described in Bleem et al. 2015 and Bocquet et al. 2019, the SPT-masses are determined using the best-fit ξ-Mass scaling relation for a flat ΛCDM cosmology with Ωm = 0.3, h=0.7 and σ8 = 0.8. Planck cluster masses are evaluated for the same cosmological parameters and the corresponding best-fit for the Y500-M500c scaling relation.

Mass-Redshift Distribution of the Planck cosmological cluster sample We plot the masses evaluated through a Monte-Carlo extraction approach, marginalizing over cosmological and scaling relation parameters, for the SPT-SZ + Planck SZ analysis described in Salvati et al. 2021.

Catalog Link

Description We provide updated cluster masses for the Planck cosmological cluster sample. For each cluster, we include position, redshift and signal-to-noise ratio as given by the Planck collaboration (Link), Best fit (suffix "bf") 68% confidence limits (suffix "low" and "up") cluster mass estimates are provided (units h-1 Msun) for M500c evaulated for 2 scenarios:
1. Marginalized over both cosmological and scaling relation parameters (labeled "M500_free"). For this scenario, in order to preserve the correlated uncertainty between different clusters, we also provide a sampled chain of cluster masses for each Planck cluster (labeled "M500_free_c"). To ensure convergence stability in the M500c evaluation we remove masses that are 5 times smaller than the best-fit value when providing the marginalized M500c. We explicitly verified that this cut does not affect final constraints on M500c or any of the results presented in the paper.
2. A flat ΛCDM cosmology with Ωm = 0.3, h = 0.7, σ8=0.8, and associated best fit fixed scaling relation parameters (labeled "M500_fixed").

Chain Link

Description : nuLCDM MCMC chain for the SPTcl+PvSPLIT dataset from "Combining Planck and SPT cluster catalogs: cosmological analysis and impact on Planck scaling relation calibration". Details of this chain can be found in Salvati et al 2021.
