SPTpol Data Products

SPTpol 500d Catalog

This page provides data products associated with the production of the SZ cluster catalog in Bleem et al. "Galaxy Clusters Discovered via the Thermal Sunyaev-Zel'dovich Effect in the 500-square-degree SPTpol Survey". These data products are produced as described in Section 2 of the paper. For more details on the conventions used in this work, and example usages of these products, see Schaffer et al. ApJ 743, 90 (2011).

If you have any questions regarding this data set or its use, please contact Lindsey Bleem (lbleem_at_anl_dot_gov).

Data products include:

1) CMB temperature maps at 95 and 150 GHz (in standard FITS format with WCS information in the header).

2) An apodization mask for the above maps, as well as the "pixel mask" that defines the cluster search region. Same format as maps, but no WCS information in the header.

3) Estimates of the noise power spectral density for these maps. Same dimensions and size as the maps, but for the corresponding Fourier-space pixels. Note that these are technically ASDs (in units of Kcmb-radians, not Kcmb²-sr).

4) An analytic approximation of the transfer function combined with measurements of the SPTpol beams. Same format as the noise psds. Note that a transfer function appropriate for power spectrum estimation of the SPTpol data will be released in an upcoming work (Chou et al., in prep).

5) A list of locations masked during the map making process (these locations will have a different transfer function than the rest of the map). In a plain text file.

6) The SPTpol 500d SZ Cluster catalog in fits format.
