Abstract
We calculate the gamma-ray lightcurves and spectra of rotation powered pulsars for a wide range of observer's viewing angles, and inclination angles of the magnetic axis to the rotation axis. We show how the shapes of the observed phase-averaged spectra as well as energy-integrated pulse profiles depend on the orientation for classical and millisecond pulsars.
