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.
