Information Re: Arecibo Proposals for the September 3, 2013 Deadline
Arecibo proposals submitted for the September 3, 2013 (17 EST), deadline
are for telescope usage during the six-month (or in some cases one-year)
period beginning January 1, 2014.
- Proposals should be prepared under the procedures detailed in
Procedures for Proposal Disposition and Telescope Scheduling.
- While a high percentage of Arecibo telescope time for radio
astronomy is presently being used for large surveys, we note that
there will be no prior preference given to survey versus other types
of proposals. We STRONGLY encourage the submission of proposals that
are not classified as surveys. Time allocation will be determined by
peer review and telescope scheduling pressure, which varies greatly
as a function of LST and day/night.
- The 700-800 MHz receiver, that was commissioned in 2009 to exploit
the temporary freeing of that band by TV channel reallocations,
has now been retired due to the reoccupation of the band by other
radio services, and is no longer available.
- For the September 3 deadline, we note the availability for
general use of the Arecibo PUPPI (Puerto Rico Ultimate
Pulsar Processing Instrument) pulsar backend, now
integrated into the Arecibo observing software CIMA.
- 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.
- 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.
