Mission
SPT

Description

From this SPT site:

The SPT-SZ 2500d SZ cluster catalog with updated calibration of the photometric redshifts and additional spectroscopic redshifts. We provide updated mass estimates using the best-fit ξ-mass scaling relation for a flat ΛCDM cosmology with Ωm = 0.3, h=0.7 and σ8 = 0.8, and mass estimates marginalized over all scaling relation and cosmology parameters from the weak-lensing calibrated cosmology analysis.

Product Name
SPT-SZ 2014 2500d Catalog
Mission
SPT

Description

The SZ selected catalog of 677 galaxy cluster candidates detected with S/N greater than 4.5 in the 2500 square degree SPT-SZ survey. For each cluster candidate the catalog provides the position, the highest detection significance in filtered SPT maps (and the core radii corresponding to the detection), the integrated Y_SZ within a 0.75 arcmin aperture, redshift information and ---for each confirmed cluster--- a mass estimate. Masses determined using the best-fit ξ-Mass scaling relation for a flat ΛCDM cosmology with Ω_m = 0.3, h=0.7 and σ_8 = 0.8 are provided in the file 2500d_cluster_sample_fiducial_cosmology.fits. Masses for the best-fit Planck cosmology are also provided, in the file 2500d_cluster_sample_planck_cosmology.fits. The data fields in these files are as described in Bleem et al. (2015). Masses derived from a velocity dispersion based mass calibration are also provided, in the file 2500d_cluster_sample_velocity_dispersion.fits. These mass estimates are marginalized over both cosmological and scaling relation parameters; the best fit values of these parameters can be found in Table 1 in Bocquet et al. (2015).

Product Name
Cluster 2010 Data
Mission
SPT

Description

We provide the first SZ selected catalog of galaxy clusters as found in Vanderlinde et al. 2010, and the covariance matrix of the mass estimates in terms of M200(rho_mean) in units of 1014 Msun h-1. The rows and columns correspond to the individual clusters, ordered as in the catalog (which is also Table D1 of Vanderlinde et al. 2010).
