INFORMATION RE-ARECIBO PROPOSALS FOR THE 1st FEBRUARY 2011 DEADLINE
Arecibo proposals submitted for the Tuesday, 1st February 2011, 23:59
EST, deadline are for telescope usage during the eight months beginning
1st June 2011 (i.e. valid for two trimesters).
- While a high percentage of Arecibo telescope time for radio
astronomy is presently being used for large surveys, we STRONGLY
encourage the submission of proposals that are not classified as
surveys. Considerable observing time (~40% of the annual radio
astronomy allocation) is assigned to such projects.
- A 700-800 MHz receiver is available for use in the band
(temporarily) freed up by TV channel reallocations in 2009.
Proposals to use this receiver are encouraged on a shared
risk-basis, subject to the evolution of band occupancy, and the
practicality of use. The RFI situation as of 12 Aug, 2009, (when
the last major TV turned off) can be seen via
RFI at 800 MHz on 12 Aug 2009
- The 2 x 7, dual-polarization, 300-MHz bandwidth, "Mock"
spectrometers are available to all ALFA users. For details see
Mock Spectrometers for ALFA users
- An implementation of a SINGLE-PIXEL MODE for the Mock spectrometers
is available. This can provide up to 1 GHz of contiguous spectral
coverage. On-line pulsar folding is not yet supported. For use of
the Mock spectrometers with a single-pixel receiver, see
Specifics for Mock Single-Pixel mode
- The WAPP spectrometer provides an 8-band, dual-polarization,
single-pixel observing capability for spectral lines or pulsars.
This mode can place 8 independent bands over a 1-GHz range, each
band having up to 100-MHz bandwidth. A contiguous 680-MHz spectral
coverage can be obtained after allowing for filter roll-off. For
an overview of WAPP capabilities, see:
WAPP spectrometer information
- Large proposals, (i.e. requesting at least 300-400 hr, though at
the NAIC Director's discretion, sometimes less than this), are
subject to skeptical review after evaluation by the normal science
referees. Progress reports for on-going large proposals will be
skeptically reviewed annually. All skeptical reviews take place in
August.
- A policy for follow-up proposals by survey consortia has been
included as Section 5.8 of the document that details information
about
Follow-up Proposal Policies.
- While we try to keep the maximum possible number of receivers cool
and ready for observing, all may not be available at any given
time. In particular, availability of the S-high and C-high
receivers cannot always be guaranteed, and these receivers will
often be scheduled in campaign mode.
