OSSE Observations of the Crab Pulsar
1994
Abstract : We present preliminary results of the Compton Gamma Ray Observatory OSSE observations of the Crab pulsar. The pulsar energy spectra and light curves are in general agreement with previous observations, validating the OSSE pulsar data acquisition modes and data analysis algorithms. The data suggest that the spectrum of the pulsar varies throughout the light curve. The "interpulse" region has a slightly flatter spectrum in the ~ 60-250 keV region and a slightly steeper spectrum at higher energies than the two main pulses. We find no evidence for any lines in the spectra with a typical sensitivity of about 10(-4) photons cm(-2) s(-1).
