SOFIA Cycle 3 German TAC Results

TAC results of SOFIA German Cycle 3 proposals

The SOFIA German Cycle 3 call for proposals (deadline July 18, 2014) generated 32 proposals. The SOFIA Time Allocation Committee (TAC) met at DSI/Univ. Stuttgart on September 17 and 18 to evaluate and rank the proposals by scientific merit.

The committee had the following members:

  • Prof. Dr. Dietrich Lemke, Chair (Max-Planck-Institut für Astronomie, Heidelberg)
  • Dr. Frank Bigiel (Institut für Theor. Astrophysik, Univ. Heidelberg)
  • Dr. Eike Guenther (Thüringer Landessternwarte, Tautenburg)
  • Dr. Mark Morris (Univ. of California Los Angeles, California)
  • Dr. Markus Nielbock (Max-Planck-Institut für Astronomie, Heidelberg)
  • Dr. Michael Olberg (Onsala Observatory, Sweden)
  • Dr. Nicola Schneider (Observatoire de Bordeaux, France)
  • Dr. Bringfried Stecklum (Thüringer Landessternwarte, Tautenburg)
  • Dr. Malcolm Walmsley (Arcetri Astrophysical Observatory, Florence, Italy)

The proposals were ranked in 5 categories:

  • A+ (excellent)
  • A- (very good)
  • B+ (good)
  • B- (fair)
  • C (poor)

Below we present tables for categories A+ (MUST DO), A- (DO with high priority), B+ (DO with lower priority). All of these proposals in the first 3 categories were awarded time, as listed. Proposals in category B- (DO if time) were not awarded time at this point. The targets in these proposals may be used as fillers, in case gaps occur in the flight plans. Proposals in category C were rejected.

The total available time for the German community in Cycle 3 is about 45 hours. It must be noted that many approved GREAT proposals request time which would require or benefit from a SOFIA deployment to the Southern Hemisphere. The time awarded here is therefore contingent on the GREAT instrument to be deployed to New Zealand, which is likely but still awaits final approval by NASA.
