VizieR Online Data Catalog: PSZ2 cluster candidates. II. (Aguado-Barahona+, 2019)
Abstract
During the second year of observations, 78 PSZ2 sources with no known optical counterpart have been observed. A robust confirmation criterion based on velocity dispersion, when available, and richness estimations enabled us to confirm 40 candidates, for which we provided 18 spectroscopic and 22 photometric redshifts.
We updated the information on 42 sources that have been validated in the original PSZ2 catalog but lacked a redshift estimate. We provided a spectroscopic redshift for 20 of them and a photometric redshift for 20 sources. We also studied the richness and applied the same criteria as for the candidates in order to check the associations with the SZ signal. We discovered that three previously confirmed counterparts were not present in the optical range studied here. (2 data files).- Publication:
