October 1, 2002
Deadline: 1 October 2002
The next deadline for observing proposals for the GBT will be 1 October 2002.
Owing to a large number of proposals already in the queue, this call will be
limited to ~500 hours of observing time, or about one-third of the last call.
Given the limited time available, the Scheduling Committee will give some
preference to meritorious programs that are time critical, such as target of
opportunity proposals and those needed for Ph.D. programs. The proposals
otherwise will be rank-ordered and selected until the available time is
exhausted. Proposals will be accepted for all standard observing modes at
frequencies through 50 GHz.
Available observing modes include spectral line, continuum, pulsar, and VLBI/VLBA.
Pulsar modes include those with the Spectral Processor, and the BCPM
(Berkeley-Caltech Pulsar Machine) through agreement with its developers.
Receivers include 290-920 MHz (PF1), 910-1230 MHz (PF2), 1.15-1.73 GHz (L),
1.73-2.60 (S), 3.95-5.85 (C), 8.0-10.1 (X), 12.0-15.4 (Ku), 18.0-26.5 (K), and
40-50 GHz (Q). Proposals requesting GBT participation in VLBA or global VLBI
observations should be submitted to the VLBA only, not to the GBT. Note that
proposals may now request the new receivers for the 910-1230 MHz (PF2) and the
40-50 GHz (Q) bands.
Commissioning of PF2 is expected to begin this autumn. Commissioning of the
40-50 GHz system will not begin until late this year, and so it is likely that
only a limited amount of observing time in this band will be available in the
upcoming term.
All proposals must be submitted electronically using version 1.1 of the NRAO
Proposal Submission Tool (PST), which is available from the downloads page. If
you have downloaded v1.1 previously, you need to download a new version of the
gbtDatan.xml file, which informs the PST of available resources, start and end
dates, etc., for each semester. This is a simple text file, which needs to be
copied to the appropriate source location for the PST to access. See http://www.nrao.edu/GBT/proposals/index.shtml
for more information.
Proposal receipt will be closed at 5 PM EDT on Tuesday, 1 October 2002.
Questions about the proposal submission process may be addressed to Carl Bignell
(304-456-2165; cbignell@nrao.edu). Technical questions about GBT hardware,
software, and observing modes may be addressed to Ron Maddalena (304-456-2207;
rmaddale@nrao.edu).
