Target list for ASCA Long Look Phase
The following is the list of targets selected for the Long Look Phase of the ASCA mission. This phase will commence upon the launch of ASTRO-E. The targets were selected from informal proposals from US and Japan (and ESA) investigators. Approximately 40 percent of the time originates in US proposals, the remainder from Japan and ESA proposals.
Targets have been given a general observing priority of A or B. Priority A targets will be observed during the first year of the Long Look Phase. If ASCA operations extend beyond the end of that year, the priority B targets may be observed. Within the general A and B categories, targets are ranked by observing priority.
The time associated with each target is the recommended observing time. Long Look observations will be performed on a "best effort" basis: previous completion criteria no longer apply. Observations may be interrupted for Observatory maintenance or TOO's.
The PI associated with each observation is the proposer. This individual serves as the planner of the observation. The PI receives no proprietary data rights --- the data flow directly into the ASCA public archive.
The latest predictions of ASCA's orbital decay suggests that stable pointing can be carried out until at least March 2001, when the satellite perigee is expected to reach 440 km. Over the subsequent year the perigee is anticipated to drop to 300 km. At some time during that year it will become impossible to maintain stable attitude, and regular observations will cease.
As the end of the first year of the Long Look Phase (and priority A obsevations) near an end, the ASCA merging committee will reconsider the priority B targets. It is possible that the committee might allow proposals for some new targets, based on results from Chandra, XMM or ASTRO-E.
