Figure 1
Light-curve and polarization results for the Crab. Results for the polarization fraction (top) and polarization angle (bottom) are super-imposed on the observed light-curve. The right-most column shows phase-integrated results. Colored overlays show the probability density distribution (see Supplementary Information) for the corresponding part of the light-curve (P1, P2, off-pulse, respectively). The off-pulse has been subtracted from P1 and P2 yielding a pure pulsar contribution. The error bars show the marginalized one standard-deviation Gaussian probability content while the magenta lines correspond to 99% upper limits (applicable to the polarization fraction only). The highest number of light-curve counts (corresponding to the peak of P1) is 2519.
