Dear ASCA users, The observation schedule for March 16 - 27 is revised as follow to get a better fit to the turn-on to the High-on state of Her X-1 in the current 35-d cycle ephemeris. The corrections are simply due to changes in the observation order. A few typos in the previous version was also corrected. F.
