SOFIA Cycle 6 German TAC Results

TAC results of SOFIA German Cycle 6 proposals

The German SOFIA Cycle 6 Open Time call (deadline July 1, 2017) attracted 27 proposals for a total of 75 observing hours available (oversubscription factor 1.8). The Cycle 6 TAC members met on Sept 12 and 13 at DSI in Stuttgart and evaluated the proposals. In summary, the TAC recommended 4 proposals as WILL DO (category I), 13 proposals as SHOULD DO (category II), and 7 proposals as DO IF TIME AVAILABLE (category III).

The committee had the following members:

Function Name Institution
Chair Hans Zinnecker Universidad Autonoma de Chile, Santiago de Chile, Chile
Reviewer Philippe Andre CEA-Saclay France
Reviewer Henrik Beuther MPIA Heidelberg, Germany
Reviewer Patrice Bouchet CEA-Saclay, France
Reviewer Jochen Eisloeffel Tautenburg Observatory, Germany
Reviewer Javier Goicoechea CSIC, Madrid, Spain
Reviewer Liugi Spinoglio INAF, Rome, Italy
Reviewer Sebastian Wolf Univ. Kiel, Germany
