SPT-3G Data Products
We provide files in a gzipped tarball, that can be added to the May 2020 version of CosmoMC to interface with the SPT-3G 2018 EE/TE bandpowers discussed above. These files include the SPT-3G likelihood, SPT-3G data (multi-frequency bandpowers, covariance matrix, bandpower window functions, beam covariance, effective band centres, and calibration covariance), batch file, a sample .ini file including the baseline priors on foreground parameters, a proposal matrix for LCDM assuming the baseline priors, and a README with instructions for how to compile CosmoMC with the SPT-3G 2018 EE/TE likelihood. If you have any questions regarding the use of this likelihood, please contact Lennart Balkenhol (lbalkenhol_at_student_dot_unimelb_dot_edu_dot_au)).
A version of the SPT-3G likelihood code in the “clik” format used by the Planck Collaboration is available on GitHub at https://github.com/SouthPoleTelescope/spt3g_y1_dist.
October 2021 Update (v3): Update to final calibration and beam covariance. This update had a negligible effect on most parameter constraints, particularly when SPT-3G and Planck are combined. See SPT page for details.
