VizieR Online Data Catalog: The SPTpol Extended Cluster Survey (Bleem+, 2020)

The SPTpol Extended Cluster Survey (SPT-ECS) is a 2770deg² that covers two separate regions of sky with low dust emission that lie north of previous areas surveyed using the South Pole Telescope (SPT): a 2200deg² region bounded in right ascension (RA) and decl. (DEC) by 22h<=RA<=6h and -40°<DEC<-20°, and a second 570deg² region bounded by 10h<=RA<=14h and -30°<=DEC<=-20°.

The survey was conducted using the SPTpol receiver that was installed on the 10m South Pole Telescope (SPT) from 2012 to 2016. The survey is composed of 10 separate ~250-270deg² "fields," each imaged to noise levels of ~30-40μK arcmin at 150GHz. See Section 2 for further explanations.

To confirm the SZ candidates as galaxy clusters, we make use of targeted optical and NIR follow-up observations, data drawn from the wide-area DES (see II/357), the Pan-STARRS1 survey (Chambers+ 2016, II/349), the all sky Wide-field Infrared Survey Explorer (WISE) data set (see II/328), and the literature.

We use the Parallel Imager for Southern Cosmology Observations (PISCO) --a new imager with a 9' field of view installed on the 6.5m Magellan/Clay telescope at Las Campanas Observatory in Chile-- to obtain approximately uniform depth griz' imaging data for over 500 SPT-selected clusters and cluster candidates. See Section 4.1.2.
