The BICEP/Keck Collaboration, Phys. Rev. Lett. 127, 151301, 2021
|BK18_bandpowers_20210607.txt||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.|
|BK18_r_likelihood_20210607.txt||Text file containing the tabulated likelihood for the tensor-to-scalar ratio, r, marginalized over dust and synchrotron foreground components, as shown with the black curve in the upper left panel of Figure 4 of BK-XIII.|
|BK18_components_20210607.txt||Text file containing the per-ell bin spectral decomposition found in Figure 16 of BK-XIII. Includes the most probable value and 68%/95% credible intervals for CMB, 95/150 GHz dust, and 95/150 GHz synchrotron components. See file header or BK-XIII for more details.|
|Text files containing average bandpass of BK18 BICEP3 95, Keck 95, BICEP2/Keck 150, and Keck 220 GHz maps.|
|BK18_cosmomc.tgz||Data and code necessary for reproducing analysis results from BK-XIII. Examples of how to run this code and reproduce the figures are included.|
|chains.tgz||CosmoMC chains of the BK18 baseline results and the joint fitting Planck 2018+BK18+BAO. They are the chains for figure 4 and figure 5 of BK-XIII respectively.|
|BK18_Nl_fsky_20210607.txt||Text file containing noise bandpowers, standard deviation of the noise bandpowers, and effective sky fraction for the BK18 BICEP3 95, BICEP2/Keck 150, and Keck 220 GHz auto-spectra. These values are shown in Figure 3 of BK-XIII.|
