BK18_Bandpowers
wget download script   curl download script
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
wget download script   curl download script
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
wget download script   curl download script
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.

BK18_Bandpass
wget download script   curl download script
Text files containing average bandpass of BK18 BICEP3 95, Keck 95, BICEP2/Keck 150, and Keck 220 GHz maps.
4 files, <10 KB
BK18_Cosmomc
wget download script   curl download script
Data and code necessary for reproducing analysis results from BK-XIII. Examples of how to run this code and reproduce the figures are included.
1 file, 10.4 MB
Chains
wget download script   curl download script
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. For large file downloads: consider a program like wget with the continue (-c) option.
1 file, 66.72 GB
Chains_No_Data_Files
wget download script   curl download script
Modified version of the full chains file, with the CosmoMC *.data files excluded to reduce file size.
1 file, 2.71 GB
BK18_NI_fsky
wget download script   curl download script
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.
1 file, 2 KB
rns_Code
wget download script   curl download script
Python code and associated files that can be used to reproduce Figure 5, constraints in the r-ns plane from BK18, Planck 2018, and BAO data.
