SPT-3G Data Products

2018 Likelihood


We provide files in a zip archive here that can be added to the June 2021 version of CosmoMC to interface with the SPT-3G 2018 TT/TE/EE bandpowers discussed above. These files include the SPT-3G likelihood, SPT-3G data (multi-frequency bandpowers, covariance matrix, band power window functions, beam covariance, effective band centres, and calibration covariance), batch file, a sample .ini file, 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 TT/TE/EE 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).
