Dear ASCA users, Thank you for your cooperation to the ASCA AO5 proposal submission. We recieved about 280 proposals to Japan time, 170 to US and 60 to ESA/Japan with about 3-4 times oversubscription in exposure time in each category. I am sending an ASCA observation schedule for September 9 -18. Crab pulsar, PSR 1821-24, and PSR 1509-58 are a series of calibration for ASCA clock and time assignment. I assume this is the final calibration for ASCA clock stability and absolute time assignment calibration. The timing calibration observations are conducted by Dr. Kawai, RIKEN. Crab Nebula is for a regular annual calibration of XRT and GIS.
