    • Synchrotron and curvature radiation are produced when a charged particle moves in the vicinity of a magnetic field. Synchrotron radiation is produced when the particle follows a gyratory path around a magnetic field line, and curvature radiation is the limit when the particle follows a curved field line. See (25) for a detailed treatment.

    • The light cylinder is defined as the distance at which the corotation velocity equals the speed of light.

    • Radio propagation through the intersteltar medium is subject to a frequency-dependent delay that is proportional to the line-of-sight electron density. This delay can be completely corrected for with the appropriate filter, and in that case it is referred to as coherent dedispersion.

    • The width of the WSRT tied-array fan beam is ∼10 arc sec, and the total contribution of the Crab nebula emission to the system temperature is ∼120 K.

    • The beaming fraction describes what fraction of the sky is illuminated by the pulsar during each rotation. It is a reasonable assumption that this fraction will be energy dependent.
