  An analysis of the publically available RXTE archive on Her X-1 including
data on 23 34.85-day cycles is performed. The turn-on times for these cycles
are determined. The number of cycles with a duration of 20.5 orbits has been
found exceedingly larger than of shorter (20 orbits) or longer (21 orbits). A
correlation between the duration of a cycle and its mean X-ray flux is noted.
The mean X-ray light curve shows a very distinct short-on state. The anomalous
X-ray absorption dip is found during the first orbit after the turn-on in the
main-on state for the cycles starting near the binary phase 0.25, while is
present during two successive orbits in the low-on state. The post-eclipse
recovery feature have not been found in the main-on state but appears at least
for two orbits during the low-on state. The pre-eclipse dips are present both
in main-on and low-on state and demonstrate the behaviour as in early
observations. The comparison of durations of the main-on and short-on states
enabled us to constrain the accretion disk semi-thickness and its inclination
to the orbital plane.
