# This file contains bandpowers and 1-sigma error for the anisotropic cosmic birefrigence spectrum
# obtained by the analysis in "BICEP2/Keck Array IX: New Bounds on Anisotropies of CMB Polarization
# Rotation and Implications for Axion-Like Particles and Primordial Magnetic Fields"
# These are the baseline spectrum (black data points) shown in Figure 1 of BK-IX.

# Column 1: multipole bin center
# Column 2: bandpower      units of degrees^2
# Column 3: 1-sigma error  units of degrees^2
