BICEP1 Three Year Data Product Details

The information on this page is taken from http://bicep.rc.fas.harvard.edu/bicep1_3yr/ BICEP's page.

Angular Power Spectrum

Text file containing frequency-combined (100+150 GHz) bandpowers and Fisher errors, corresponding to the filled circles in Figure 5 of Barkats et al. TB and EB bandpowers will be available shortly.

Bandpower Window Functions

Tarball containing the bandpower window function for each of the 9 l bins

BB Upper Limits

Text file containing 95% confidence level upper limits derived from the bandpower likelihood functions. See Section 9.1 of Barkats et al.

r Likelihood

Text file containing the tabulated likelihood for the tensor-to-scalar ratio, r, computed using the "direct likelihood calculation" described in Section 9.3.1 of Barkats et al.

Systematic Uncertainties

Text file containing fractional uncertainties on bandpowers due to systematic error in absolute gain calibration and beam width calibration.

Bandpower Likelihoods

Tarball containing data necessary for constructing bandpower likelihoods following the method of Hamimeche & Lewis (2008). See Section 9.1 of Barkats et al. File contains:

• B1_3yr_likelihood_bandpowers_20131003.txt
• B1_3yr_bpcm_20131003.txt
• B1_3yr_bpcm_no-sysuncer_20131003.txt
• directory for bandpower window functions

Bandpower Likelihood Code

Gzipped tar archive containing python code and the relevant above data products to calculate the Hamimeche&Lewis likelihood. The python code also contains a specific wrapper to generate the HL likelihood versus r using the BB spectrum. et al.

Theoretical Power Spectra

Tarball containing theoretical power spectra for the E-no-B and B-no-E models, described in Section 5.3 of Barkats et al. Includes both the unbinned spectra calculated by CAMB as well as the binned expectation values of the bandpowers. File contains:

• camb_wmap5yr_noB_uK.txt
• camb_wmap5yr_withB_uK.txt
• BICEP_20131003_cl_expected_noB.txt
• BICEP_20131003_cl_expected_withB.txt
