SOFIA Cycle 4 German TAC Results

TAC results of SOFIA German Cycle 4 proposals

The SOFIA German Cycle 4 call for proposals (deadline July 10, 2015) generated 30 proposals. The SOFIA Time Allocation Committee (TAC) met at DSI/Univ. Stuttgart on September 1 and 2 to evaluate and rank the proposals by scientific merit.

The committee had the following members:

Chair Quirrenbach, Andreas LSW Heidelberg
Reviewer Boehnhardt, Hermann MPS, Goettingen
Reviewer Cesaroni, Riccardo Arcetri, Florence
Reviewer Glover, Simon ITA, Heidelberg
Reviewer Kramer, Carsten IRAM 30m, Granada
Reviewer Lis, Darek LERMA, Obs. de Paris
Reviewer Schneider, Nicola Obs. Bordeaux
Reviewer van der Tak, Floris SRON, Groningen
Reviewer Testi, Leonardo ESO/ALMA


The proposals were ranked in 5 categories:

  • 5. Must do
  • 4. Should do
  • 3. Do if time
  • 2. Filler
  • 1. Don't do

Below we present tables for categories 5 (Must do), 4 (Should do) and 3 (Do if time). The entries per table are sorted alphabetically by PI name and do not represent a ranking within the category.

Category 5: Must do proposals

(*) This joint impact proposal was strongly endorsed by the U.S. selection process.

Category 4: Should do proposals

(**) As this joint impact proposal was declined in the U.S. selection process, by the rules it is automatically declined in the German selection process.
