SPT-3G Data Products


We provide the foreground-subtracted minimum-variance combination of the SPT-3G 2018 multi-frequency band powers. The band powers cover the angular multipole range 750 < ell <= 3000 for TT and 300 < ell <= 3000 for TE and EE in bins of delta_ell = 50 for ell < 2000 and delta_ell = 100 for 2001 < ell. The band powers, band power errors (both in D_ell in units of uK2), and associated band centers, are provided for plotting in a text file here. Each row is one ell-bin. The columns are (1) ell_min, (2) ell_max, (3) TT ell_center, (4) TT, (5) sigma_TT, (6) TE ell_center, (7) TE, (8) sigma_TE, (9) EE ell_center, (10) EE, (11) sigma_EE. If you have any questions regarding this data set or its use, please contact Lennart Balkenhol (lbalkenhol_at_student_dot_unimelb_dot_edu_dot_au).
