# BICEP2 2014 Data Release # The BICEP2 Collaboration, BICEP2 2014 I: DETECTION OF B-mode POLARIZATION AT DEGREE ANGULAR SCALES # http://bicepkeck.org/bicep2_2014_release/ # # File: B2_3yr_likelihood_bandpowers_20140314.txt # Date: 2014-03-14 # # BICEP2 actual and simulated bandpowers necessary for Hamimeche-Lewis bandpower likelihood approximation. # See Section 9.1 of Barkats et al. (2014) for details. # Note that a separate file containing the likelihood for the tensor-to-scalar ratio, computed without this approximation, is available (B2_3yr_rlikelihood_20140314.txt). # # Bandpowers are organized into one matrix per ell bin. # Each matrix is symmetric 3x3: # | TT TE TB | # | TE EE EB | # | TB EB BB | # However, for this release bandpowers TT, TE, and TB are not available because our constrained T simulations do not include appropriate sample variance. See Section 5.1.1 of BICEP2 2014 I for more details. # Note also that our polarization angle calibration removes any polarization rotation from the EB spectrum. # In all cases, bandpowers represent ell*(ell+1)C_{ell}/(2*pi). # Units are uK^2 CMB. # 1. # Fiducial model bandpowers D^f # Calculated as the ensemble average of signal+noise simulations. # Noise bias is included. # Bin 1 (ell~45.1) NaN NaN NaN NaN 9.5617e-02 3.5692e-04 NaN 3.5692e-04 5.3043e-03 # Bin 2 (ell~73.9) NaN NaN NaN NaN 3.5677e-01 -1.4423e-04 NaN -1.4423e-04 8.2475e-03 # Bin 3 (ell~109.1) NaN NaN NaN NaN 8.3932e-01 5.7815e-05 NaN 5.7815e-05 1.6408e-02 # Bin 4 (ell~144.2) NaN NaN NaN NaN 1.1652e+00 -1.0019e-05 NaN -1.0019e-05 2.9111e-02 # Bin 5 (ell~179.1) NaN NaN NaN NaN 9.3285e-01 -1.9071e-03 NaN -1.9071e-03 4.9792e-02 # Bin 6 (ell~213.7) NaN NaN NaN NaN 1.0038e+00 7.5299e-04 NaN 7.5299e-04 8.0567e-02 # Bin 7 (ell~248.4) NaN NaN NaN NaN 2.4169e+00 -2.8519e-03 NaN -2.8519e-03 1.3109e-01 # Bin 8 (ell~283.1) NaN NaN NaN NaN 6.0171e+00 -1.2815e-03 NaN -1.2815e-03 2.1434e-01 # Bin 9 (ell~317.4) NaN NaN NaN NaN 1.1823e+01 4.1132e-03 NaN 4.1132e-03 3.5356e-01 # 2. # Data bandpowers \hat{D} # Real data bandpowers from BICEP2 three-year result. # These differ from bandpowers displayed in Figure 2 of BICEP2 2014 I, because noise bias is included here. # Bin 1 (ell~45.1) NaN NaN NaN NaN 1.6192e-01 1.4340e-02 NaN 1.4340e-02 1.3266e-02 # Bin 2 (ell~73.9) NaN NaN NaN NaN 5.1594e-01 2.9499e-03 NaN 2.9499e-03 1.9672e-02 # Bin 3 (ell~109.1) NaN NaN NaN NaN 9.2978e-01 1.0768e-02 NaN 1.0768e-02 2.7545e-02 # Bin 4 (ell~144.2) NaN NaN NaN NaN 1.0792e+00 2.7370e-03 NaN 2.7370e-03 3.6610e-02 # Bin 5 (ell~179.1) NaN NaN NaN NaN 6.5833e-01 -3.1405e-03 NaN -3.1405e-03 6.0254e-02 # Bin 6 (ell~213.7) NaN NaN NaN NaN 1.0237e+00 5.8608e-02 NaN 5.8608e-02 9.9342e-02 # Bin 7 (ell~248.4) NaN NaN NaN NaN 2.1939e+00 -3.8797e-02 NaN -3.8797e-02 1.6139e-01 # Bin 8 (ell~283.1) NaN NaN NaN NaN 6.7952e+00 -5.5790e-02 NaN -5.5790e-02 2.2162e-01 # Bin 9 (ell~317.4) NaN NaN NaN NaN 1.4033e+01 9.9068e-02 NaN 9.9068e-02 3.5396e-01 # 3. # Noise bandpowers N, including instrumental noise and E->B leakage. # Calculated from the ensemble average of noise-only simulations (and signal-only simulations for E->B leakage). # Subtracting these bandpowers from the real data bandpowers listed above will recover the BICEP2 three-year bandpowers from Figure 2 of BICEP2 2014 I. # Bin 1 (ell~45.1) NaN NaN NaN NaN 5.8716e-03 -6.4317e-06 NaN -6.4317e-06 4.6169e-03 # Bin 2 (ell~73.9) NaN NaN NaN NaN 7.0994e-03 3.0775e-05 NaN 3.0775e-05 6.4091e-03 # Bin 3 (ell~109.1) NaN NaN NaN NaN 1.3297e-02 6.2562e-06 NaN 6.2562e-06 1.2552e-02 # Bin 4 (ell~144.2) NaN NaN NaN NaN 2.3873e-02 9.4600e-05 NaN 9.4600e-05 2.2729e-02 # Bin 5 (ell~179.1) NaN NaN NaN NaN 4.1451e-02 -1.6565e-04 NaN -1.6565e-04 3.9607e-02 # Bin 6 (ell~213.7) NaN NaN NaN NaN 6.9775e-02 -1.7600e-04 NaN -1.7600e-04 6.5596e-02 # Bin 7 (ell~248.4) NaN NaN NaN NaN 1.1443e-01 -3.3520e-04 NaN -3.3520e-04 1.1074e-01 # Bin 8 (ell~283.1) NaN NaN NaN NaN 1.9510e-01 -2.7972e-04 NaN -2.7972e-04 1.8816e-01 # Bin 9 (ell~317.4) NaN NaN NaN NaN 3.2633e-01 -2.8851e-04 NaN -2.8851e-04 3.2137e-01
