ASCA workshop on instruments calibration

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

Dear ASCA team members and ASCA users,

We are having an ASCA workshop on instruments calibration
on December 6-7, 1995, at ISAS. Attached below ia a preliminary
program of the meeting. We welcome comments on the problems related
with the ASCA instrument calibration. Since we reserve lot of time
for discussion, 5-min comments with 2-3 view graphs are available.
Those who has provided such a short comment can contact with the
chairperson of the session you wish to talk. 

Comments on the test of extended source analysis tools, fine calibration
at the Si, Au edges around 2 keV, the SIS pile-up effect and its correction,
further calibrations and software developments etc. are encouraged.

Regards,
F. Nagase
