Song, Li-Ming; Wu, Mei; Ma, Yu-Qian +4 more

Timing and spectral analysis of COS-B and HEAO-B satellite data of the pulsar Geminga are presented. The results confirm that Geminga is a pulsar with a strong gamma emission and a weak X-ray emission. A phase histogram of Geminga in different energy ranges from a summation of four COS-B observations is given.
