Observation of the VELA gamma-ray pulsar with the GAMMA-1 telescope.
Abstract
Observations of PSR0933 with the GAMMA-1 telescope in the summer of 1990 and spring of 1991 are presented. The mean 300-5000 MeV flux of the whole pulsed emission is found to be consistent with the time-averaged COS-B result. The 30-300 MeV flux suggests that the pulsar was observed in a low intensity state. The emission from the first peak appears softer than the second peak. The variation of the spectra over time is investigated.
