Long-term observations of Her X-1 with BATSE

Pulsed emission from Her X-1 has been observed by BATSE during each Main High state throughout the CGRO mission. This long observation set by a single instrument provides new information on long-term behavior of the Her X-1 system. The pulsed emission varies by more than a factor of 3 between different Main High states. Frequency and flux histories do not show a simple relationship between the source intensity and spin behavior, but do show that the source is normally in spinup, and spindown episodes occur at all source flux levels. Orbital analyses are presented, including determination of the orbital period derivative, which is in agreement with Deeter et al. (1991).
