Dear ASCA users, I am sending an ASCA observation schedule for March 16 -27. The observation of G359.1-0.2 is split into two exposures to allocate the calibration observations of Her X-1 in its High-on, non-eclipse phase. The Her X-1 observations aim to calibrate low energy point spread functions at several offset positions. F.
