AO1/AO2 supplemental



Dear ASCA users:

We have almost completed the calculation of exposure time for observations
between 1993 October 26 and 1994 July 21. The calculation of 
the exposure time is based on the GIS data (it is our agreement that
ASCA observation completion is judged byusing the GIS data).

After examine the list, I found that the exposure for some targets
are extremely below the completion criteria (95% for priority-A and 75%
for priority-B and -C). In addition to already supplemented targets
I have assigned further additional observations for the targets shown
in the following list. In the list, some targets which were scheduled
but not observed due to operational trouble are also listed.

Reobservations of previously failed targets and supplemental
observations for the targets for which previous observations were 
insufficient will be scheduled in the forthcoming earliest visible
windows of these targets.

I welcome and appreciate if someone withdraw the supplemental observation
in the case when the previously obtained data are satisfactory to
achieve the proposal purpose. 

If we find further insufficient observations during the period after
July 21, 1994, we will supplement such insufficient observations in the
earliest opportunity of the next visible window.

Regards,
Fumiaki
