Multi-wavelength Time Allocation, the Wave of the Future.

B. Blacker, D. Macchetto, C. Urry, and B. Wilkes


With the successful launch of NASA's third "Great Observatory", the
Chandra X-ray Observatory (formerly AXAF), we are embarking on a new
era of multi-wavelength science campaigns from space.  To meet this
challenge, the Space Telescope Science Institute (STScI) and the
Chandra X-ray Center (CXC) have initiated a test program whereby
proposals of a multi-wavelength nature requiring both HST and Chandra
data can be submitted to either the HST Review Panel or the Chandra
Review Panel.  This joint activity enables proposers to avoid the
"double jeopardy" of submitting to two separate reviews. By agreement
with the CXC, STScI will award up to 400 kilo-seconds of Chandra
observing time, and similarly the CXC will award up to 100 orbits of
HST time (about one week of observing time for each observatory).  The
only criterion above and beyond the usual review criteria is that both
sets of data are required to meet the scientific goals.

We discuss the multi-wavelength allocation concept, how the process
worked for HST's Cycle 9 Review and modifications for Chandra's Cycle
2 Review.  We will also address other missions, such as EUVE, FUSE,
NOAO, SIRTF and NGST, that might be included in coordinated
observation time allocation in the future.
