George Sonneborn Memo requesting updates
Instructions for making target changes
The following lists are provided for reference by users considering target changes in response
to the Feb. 2002 Project Call for Target Updates.
Note: Some targets may appear in both lists (if previous observations have occurred but a pending
observation exists). Also, pending lists contain `placeholder' observations for some programs
with targets on hold for various reasons.
Target Changes are Requested by March 20, 2002.
As discussed in the memos linked above, target updates are being allowed in two areas:
- Target changes for "pending" targets, where objects at substantially higher (absolute) declinations
may be substituted for targets at lower declinations; and
- Observatory program (Supplementary) targets to increase the pool of targets
available at higher declinations.
The lists linked above can be used to check for your unobserved targets, as well as check whether your
potential new targets are already in the system. In addition, the current listing of
Observatory program targets is available and will be updated regularly with new submissions.
Instructions for submitting new targets at this time are given in the instructions memo.
Observatory Programs
The Z9xx programs defined to date were selected with the following criteria in mind:
Programs are aimed at providing databases useful to the community at large. (Selection
was based on target classes, not individual targets.) We selected target-classes that have
not been fully explored by the existing PI/GI programs, but which warrant such exploration.
We chose exposure times that will yield either useful spectroscopic data directly, or for
faint targets, solid flux measurements to guide future proposers (e.g. "snapshots").
We now solicit additional target classes from the community at large to expand the pool
of targets available above absolute values |dec| = 40 degrees. Your selections should
follow the criteria outlined above. Suggestions of additional targets for currently defined
programs will also be considered.
The current Observatory programs that have been defined are:
-
Z901: Survey of ISM sight lines. Targets based on the HST cycle 8, NWU,
snapshot survey of ISM towards O and B stars. Total number of targets in
program 90. Exposures calculated to yield S/N=30 in combined spectra.
-
Z902: Survey of Algol binaries. Target list based on; Budding's
"A Catalogue of Classical Evolved Algol-Type Binary Candidate Stars" Total
number of targets in program: 26, targets are intended to be monitored at
irregular intervals. Exposure times calculated to yield S/N of 30, but no
longer than 4 ksec.
-
Z903: Survey of White Dwarfs from the McCook and Sion Survey. Targets in
program 2. Exposure times calculated to achieve S/N=20, but no longer than 10
ksec. (George: we delivered this one with only two as the MP needed them. Jean
is still looking into adding more)
-
Z904: Survey of O-B subdwarfs. Target list based on the Kilkenny, Hener &
Drilling catalog. Total number of targets in program: ~60. Exposure times
calculated to achieve S/N of 20, but no longer than 10 ksec.
-
Z905: Survey of Ae/Be stars.
Primarily aimed at establishing observed continuum fluxes of a set of these
stars at ~1050 Angstroms. Targets were selected from the samples of Corporon & Lagrange
1999, Hamann & Persson 1992, Hillenbrand et al.1992, Lienert et al. 2001 and
Testi et al. 1998. Exposure time (with one exception) of 10 ksec. Survey
contains 13 targets.
