  1. Survey designed based on UW-Madison strategic planning. Adjusted for WIYN by Eileen Friel (Indiana) Analysis: Eric Hooper & Michelle Wojtaszek (UW-Madison) February 28, 2013 Selected Preliminary Results of the WIYN Survey

  2. Brief Overview of the Survey • Responses from Wisconsin, Indiana, NOAO, and national users of WIYN. Yale is conducting their own. • 27 responses: 8 (UW); 11 (IU); 8 (other). • 27 responses: 10 (faculty); 4 (scientists); 4 (postdoc); 8 (grad student); 1 (unknown). • Three sections: name & demographics; plans over the next two years; future directions (5 years). • Mix of numeric and free response questions. • For numeric responses, the higher values are more superlative (more important, greater, etc.)

  3. Summary of Selected Questions Near term (2 years) • Importance of the various instruments. • Importance of 0.9-meter. • Operational modes; concerns; recommendations; positive qualities of the telescope / operation. Longer term (5 years) • Types of observing and wavelength. • Spectral resolution (optical and infrared). • Observing facilities; new WIYN partners; large surveys; joint observing; WIYN general or special purpose.

  4. Near Term: Question 1 (Instrument Importance)

  5. Near Term: Question 3 (0.9-meter Importance)

  6. Longer Term: Question 9a (observing modes)

  7. Longer Term: Question 9b (observing type)

  8. Longer Term: Question 10 (wavelength)

  9. Longer Term: Question 11 (resolution)

  10. Short Response: Q. 5 (concerns) Queue based observing program would be useful for time domain studies. WHIRC throughput issue. Broken fibers on Hydra. Reduce background @ K band introduced by WTTM if feasible. Integrate new IFUs that utilize WIYN's superior image quality. Support for grating structure changes during night/run.

  11. Short Response: Q. 6 (instr. / telescope) More funding/scholarships for students to visit Kitt Peak in person. Complete ODI (also: give up on local OTA model). Pipeline for WHIRC reduction. Endorse the current work of Kotulla to improve imaging data reduction software. Investigate adding 1-2 more CCDs (plus optics) so Hydra users can simultaneously obtain 2-3 orders. Would make WIYN-Hydra more competitive. Long-slit spectrograph.

  12. Short Response: Q. 7 (observing modes) Schedule WIYN as one entity across all partners. Allocate time as is now done, but schedule as one. WIYN could be an important platform for follow-up and/or initiating deeper surveys or surveys in other near-IR bands (notably J and K). Similarly, interesting objects found by APOGEE could be followed up in the optical with either Hydra or a separate very high-resolution spectrograph. For remote observing-a service mode for pODI/ODI.

  13. Short Response: Q. 8 (WIYN likes) Excellent staff (cited multiple times!). Learning opportunities/convenient location. Gain in valuable observing skills. Efficient and highly productive. Broad range of instrument capabilities. Remote observing is convenient and saves travel costs. Image quality over a wide field.

  14. Short Response: Q. 16 (specialize / general ) Specialize / keep general (both responses). An optimal mix of a few workhorse instruments and 1 or 2 with unique capabilities. Overspecialization / compartmentalization can impede progress-a breadth of knowledge can → new connections; might otherwise go unobserved. Focus on major projects (but some small projects). Limiting capabilities will not serve diverse needs of many WIYN users. Encourages smaller-scale instrument programs; useful for training next gen. of instrument builders.
