Dear ASCA users, I am sending an ASCA observation schedule for the period of September 27 to October 9. In this week, we allocate an instrument calibration with Crab Nebula. In addition to the regular calibrations for XRT and GIS, we are planning to measure in detail the pattern of stray light using offset pointing of the Crab Nebula. F.
