BATSE Pulsars
Her X-1 Flux/Frequency History (recent)

This source has a period less than the Nyquist limit of 2.048s for the DISCLA data used by the Monitor, so the measured power is severely reduced due to aliasing. The flux has been corrected by a factor of 5.0 to obtain the values plotted.
Eclipses in Her X-1 are not accounted for in this flux history.
