asca timeline

[WHITE@LHEAVX.GSFC.NASA.GOV (Nick White, HEASARC/ASCA-GOF NASA/GSFC)]

Dear ASCA team members and ASCA users:

I am sending the short-term observation schedule of ASCA in which the 
observation plan for the week of November 3-11 is updated. In the column 
of comments, PV means the performance verification observations by the 
team, JPN; Japan time, US; US time, JUS; collaborative Japan/US time 
leading by Japanese PPI associating with US Co-PI, and USJ; collaborative 
US/Japan time leading by US -PPI associating with Japanese Co-PI.

The two months from October 15 to December 14 are designated to be a 
transient period moving from the PV observations to the AO1 guest 
observations. Hereafter,  PV observations will be gradually decreased and 
GO observations will be increased in the two months. After December 15, 
the observation time will be fully occupied by GOs except for the 
observatory-time observations (i.e., satellite maintenance, instruments 
check-out and calibration, TOO observations). 

The short-term observation plan for a week will be announced every week 
for about two weeks prior the operation. The long-term timeline for the half-
year interval of AO1 will be released in a week or two, when we finished 
adjustment between the PV and GO observations. In the present tentative 
timeline prepared using the automatic scheduling system, SPIKE, we failed 
to allocate for about 10 priority-B targets in the AO1 period (all priority-A 
targets are in the time line and about 10 priority-C targets are instead in the 
timeline at present). We are now investigating further modification of the 
timeline to minimize the number of priority-B targets that are carried over to 
the next AO period.
