SPT-3G CMB Lensing Reconstruction from Summer Survey

This page provides data products associated with the CMB lensing power spectrum measurement using observations from two years of SPT-3G summer field survey over roughly 2640 square degrees described in Levy et al. (2026). The reconstructed CMB lensing and curl power spectra and covariance matrices are presented over the multipole range 50 < L <= 2000. Files are provided combining measurements across fields and for each of the three SPT summer fields (labeled A, B, and C) separately. The columns of the Bandpowers files are L_{eff}, C_L^{KK}, and ΔC_L^{KK}.
