ASCA Workshop on Instrument Calibration

Dear ASCA users,

We are having a meeting on ASCA instrument caribrations at ISAS on
December 6-7 to review current status of ASCA calibration.
Followings are the preliminary agenda of the meeting. We welcome
your comments and suggestions. Please send your comments to N. White
or me prior to the meeting if you have issues related to calibration and
you cannot attend the meeting. If we recieve some important issues
we will try to include those into the discussion items.
