Dear ASCA users: I am sending ASCA observation schedule for the period of September 6-17. We allocate a 10-ks supplemental observation for incomplete AO-1 observation of W28. Sometime ago I was recommended by R. Mushotsky, a member of ASCA Scientific Advisor's group, to confirm low energy response of SIS sensors by using the observation of 3C58. In this week we have allocated a 30-ks guest observation of 3C58 (PPI; Torii, Co-PI; Slane). They are observing the source by 1CCD mode with nominal chip. To calibrate other three chips in each SIS sensor, I have added 60-ks calibration observation for the source. Dr. H. Tsunemi, a leader of the project and a core member of the SIS team, is willing to offer their data for SIS low energy calibration. I will ask him to organize a task team for SIS low energy response confirmation using both the GO and Cal data of 3C58, including K. Mitsuda, T. Dotani and a few SIS team members as well R. Mushotsky, K. Torii and P. Slane in the team. F.
