  In recent years, surprise discoveries of pulsed emission from the Crab and
Vela pulsars above 100 GeV have drawn renewed attention to this largely
unexplored region of the energy range. In this paper, we discuss example light
curves due to curvature emission, with good resolution in the different energy
bands. Continued light curve modelling may help to discriminate between
different emission mechanisms, as well as constrain the location where emission
is produced within the pulsar magnetosphere, including regions beyond the light
cylinder.
