Scientific Productivity of SOFIA

1 Scientific Productivity of SOFIA William T. Reach SOFIA Users Group #9 November 2015

2 Measuring Productivity 1. Status of GI Projects Allows interaction with GIs, assessment of needs, ability to determine corrections to policies 2. Publications Measures rate of production of scientific results and their impact. 3. Production split by SI Allows assessment of scientific production by instrument to inform decisions related to the instrument suite. 2

3 1. Status of Guest Investigator Projects Each project dispositioned into one of these categories: Published: refereed journal article using data Ongoing: will be combined with upcoming observations In preparation: GI working on draft/plans to write Not reduced: calibrated data not yet available Incomplete: less than half of proposed observations complete, or GI indicates cannot publish subset Unpublishable: GI or SMO believe scientific results will never be obtainable with the acquired data 3

4 (accepted projects that got some data) no status unpublishable incomplete published in preparation ongoing 4

5 Cycle 1 no status published no data unpublishable incomplete in preparation 5

6 Cycle 2 no status no data published unpublishable incomplete FIFI LS not reduced in preparation 6

7 Implications of Project Status Study Incomplete projects squandered SOFIA time 12% of BS-Cycle2 proposals incomplete Observatory reliability: 89% dispatch rate If we plan for 100% of time, many programs will be incomplete Mitigations are now in place for incompletions For Cycle 4, we scheduled contingency flights, to be used when a flight is cancelled. Including 1 contingency for 10 flights should account for isolated missed flights. Contingencies already exercised in OC4A, OC4B, OC4D (tonight) For Cycles 3 and 4 we also carry over the highest-ranked observations to following Cycles Top 5% are considered guaranteed 7

Publications Publication tracking is on our website; new database Allows tracking and linkage to features of Data Cycle System Target publications per hour Metric in the SOFIA Outreach Plan: 20 hrs/paper Count all science flights with 8 hrs/flight Through end of 2015: Already at 18.9 hrs/paper Maintaining rate, with 808 RH expect 43 papers from Cycle 4

10 Publication rate 80 Cumulative Publications 60 projection Prediction for 2016 scales to 12 months from actual publications as of 5/1/16 Using publications/hour method, predict 10 more papers in CY16 10

15 Summary: Measuring Productivity 1. Status of GI Projects Implemented mitigations to improve GI project completion. Beginning to collect status for Cycle Publications Slow by steady increase in SOFIA publications. 3. Production split by SI Publications arise predominantly from FORCAST and GREAT, which have established communities. 15
