SOFIA Cycle 1 German TAC Results

TAC results of SOFIA German Cycle 1 proposals

The SOFIA German Cycle 1 call for proposals (deadline March 2, 2012) generated 39 proposals, asking for a total of 200+ hours observing time. The SOFIA Time Allocation Committee (TAC) met at DSI/Univ. Stuttgart on April 16 and 17 to evaluate and rank the proposals by scientific merit.

The committee had the following members:

  • Prof. Dr. Michael Grewing, Chair (Univ. Tübingen, Germany)
  • Dr. Pierre Cox (IRAM Grenoble, France)
  • Dr. Andy Harris (Univ. Maryland, USA)
  • Dr. Frank Israel (Leiden Observatory, The Netherlands)
  • Dr. Hans-Ulrich Käufl (ESO, Garching)
  • Dr. Jesús Martin-Pintado (Centro de Astrobiologia, Madrid, Spain)
  • Dr. Katharina Schreyer (Univ. Jena, Germany)
  • Dr. Bingfried Stecklum (Landessternwarte Thüringen, Tautenburg, Germany)

The committee was asked to rank the proposal into 3 main categories:

  • category A (MUST DO)
  • category B (CAN DO, if time)
  • category C (DON'T DO in this cycle)

Interestingly, the panel decided to introduce a 4th category, intermediate between A and B, labelled A/B (SHOULD DO, if at all possible).

Below, we present 3 tables, one for category A, one for category A/B, and one for category B. The order of appearance of the selected proposals in each table is alphabetical and does not represent a ranked sequence. The total open time available for the German community is about 35 hours.

Update: On recommendation from the SOFIA Users Group (SUG) the Science Mission Operations has decided to publish the time awarded for each proposal. Thus, we now list the awarded hours by the TAC in the last column.

While we will make every effort to schedule all category A proposals, in the end it all depends if they can be fitted into an optimised flight schedule. Therefore it is conceivable that a category A/B or even B proposal will make its way into the schedule, while a more meritorious A proposal may have to be left out. Note that we plan to have a SOFIA deployment to the southern hemisphere in July 2013 (most likely Christchurch, New Zealand).

Thank you very much for your interest in SOFIA observations.
