Planck Cluster Catalog

An Extension of the Planck Cluster Catalog (Burenin 2017)

Description

Burenin (2017) presented a catalogue of galaxy clusters detected in the Planck all-sky Compton parameter maps and identified using data from the WISE and SDSS surveys. The catalogue comprises about 3000 clusters in the SDSS fields. The completeness of this catalogue is expected to be high for clusters with masses larger than M₅₀₀ =~ 3x10¹⁴ Msun, located at redshifts z < 0.7. At redshifts above z=~0.4, the catalogue contains approximately an order of magnitude more clusters than the 2nd Planck Catalogue of Sunyaev-Zeldovich sources in the same fields of the sky. This catalogue can be used for identification of massive galaxy clusters in future large cluster surveys, such as the SRG/eROSITA all-sky X-ray survey.

The catalog of identified clusters is presented in the ascii file cl_table.dat. It contains the following fields:

(1) Number of the source
(2) Source right ascension (J2000)
(3) Source declination (J2000)
(4) Signal-to-noise ratio in the y parameter map
(5) Declination shift of the optical center relative to the center of the SZ source, in arcmin
(6) Right ascension shift of the optical center relative to the center of the SZ source, in arcmin
(7) Cluster redshift z, * indicates a photometric redshift estimate
(8) Number of galaxies used to obtain z
(9) Source name in the PSZ2 Catalog, ** indicates two or more clusters at different redshifts are found in the SZ source
field. The SZ source is identified with the cluster with the largest mass estimate from SDSS and WISE data.
