Hello all,
To date, we have had 4 clusters proposed to fill the 15 available free
orbits of HST time:
Cluster z
dates schedulable orbits
cl1604+43 0.92 (1.25 in background) present
- 6/6 9
XMM#2 1.2
11/28 - 3/27 7
1214_7.2 1.1
12/10 - 5/20 7 + 1 with gaps that need to be
tested/fixed
1214_7.4 1.1
12/10 - 5/20 8?
RCS: Still waiting for candidates, preferably in spring time slots
CL1604+43: has background cluster at z=1.25, FOV covers ~30
spectroscopically confirmed cluster members + 5 spectroscopically
confirmed background cluster members. Background cluster appears fairly
massive but specroscopy is sparse due to slit mask constraints.
Concerns about lensing effects in background cluster.
1214_7.2 and 1214_7.4: two of the four most significant cluster
detections in the IRAC sample
XMM#2: X-ray discovered, comparable in mass and luminosity to XMM2235
included in proposal
There is very little time left to schedule these. Tomorrow (Thursday),
STScI will schedule the week of 11/28 - 12/4. Given that constraint,
we have made one decision and submitted the XMM cluster proposed by
Chris Mullis for observing. If anyone sees a serious problem with this,
there is still time to cancel the observations. Scheduling this cluster
leaves ~8 orbits available for one additional cluster to be scheduled.
All of the proposed clusters are visible in the next couple weeks, so we
are asking for input as soon as possible from the rest of the
collaborators on how to proceed
