Pulsar Efficiency
  Pulsar efficiency, defined as the ratio of the pulsed bolometric luminosity to the spin-down power, is calculated to be about 15% (averaged over the spin-dipole inclination angle, ranging between about 50% for the aligned and 10% for the orthogonal). We also estimate the characteristic photon energy and argue that our results agree with the Fermi pulsar catalog -- in a sense.
