ASCA weekly

[Fumiaki NAGASE <nagase@astro.isas.ac.jp>]

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.
