BK18_Bandpowers
 Text file containing bandpowers and error bars for all BB spectra used in the BK18 likelihood analysis. Bandpowers are specified as 𝓁 (𝓁+1) C𝓁 / 2π in units of μK2. These are the same data as shown in Figure 15 of BK-XIII, except that figure uses 100 𝓁 C𝓁 / 2π. The error bars include sample variance corresponding to the maximum likelihood lensed-ΛCDM+r +dust+synchrotron model, as in Figure 15.

Bandpowers
 Text file containing bandpowers and error bars for all BB spectra used in the BK15 likelihood analysis. Bandpowers are specified as ℓ (ℓ+1) Cℓ / 2π in units of μK2.
