ASCA weekly
Dear ASCA users:
I am sending an ASCA observation schedule for the period of May 8 - 18.
The 29-ksec exposure of Cyg X-1 is a supplemental observation for the
XRT PSF (point spread function) calibration. A plan of ASCA calibration
observations hereafter during the AO3 period is attached below the weekly
shcedule. We also include an AO2 hold-over target, X2127+119.
I also attached a list of supplemental observation targets. This listing
is based on the observation journal recently released. I have searched
targets real exposure time significantly smaller than the approved
time upto the end of February 1995with and listed those targets which
need more than 5 ksec additional exposure (No supplement is planned for
time critical (coordinated simultaneous) observations even if the achieved
exposure is significantly smaller than the approved exposure time).
