Overview

 

This page provides data products associated with the point-source catalog from 2530 square degrees of SPT data described in Everett et al. (2020). Linked below are the full three-band source catalog (down to a significance threshold of 4.5 sigma), the differential number counts in each band---total and divided into synchrotron- and dust-dominated counts---and the cumulative number counts in each band.

If you have any questions regarding this data set or its use please contact Wendy Everett (wendeline.everett_at_colorado.edu).
