Action Items from ODI Meeting, December 14-15, 2000

1) Review WIYN wavefront errors for evidence of a constant term that may be removable with a new corrector. (Claver)

2) Determine if secondary mirror vacuum support relies on absolute or relative pressure sensors (Claver)

3) Check CTIO corrector for (a) cost, (b) throughput versus wavelength (Claver)

4) Contact Dan Weedman for advice on ODI funding strategies with regard to (a) perception that WIYN=NOAO within NSF, (b) merits of ATI vs MRI vs both (Jacoby) Done -- see details in NSF Visit Report.

5) Verify that Bob Eisenstein will be at NSF during January visit (Jacoby) Done -- He was there.

6) Discuss possible participation on technical advisory committee with Tony Tyson (Tonry) Partly Done -- Tony is interested in joint detector issues

7) Ask Steve Zepf for the NSF reviewer comments on his ATI proposal, and prepare arguments why they are inappropriate (Jacoby)

8) Is Jacoby's salary paid by NOAO or AURA? (Green) Done -- Jacoby works for WIYN but is paid by NOAO.

9) Ask NSF for status of TSIP program - will it be defined before March WIYN Board mtg? [The point here is to be able to discuss with the Board the necessary time offerings for an instrument grant.] (Jacoby) Done -- The TSIP program remains undefined and according to its original description, was not intended to fund instrumentation for telescopes smaller than 6.5-m.

10) Investigate large filters - are they available from (a) Andover, (b) REOSC (or whomever Christian Veillieut indicates) ? (Jacoby) Done -- Andover claims to be able to make filters from Schott glass that are large enough for ODI, but interference filters are made from mosaics of ~5-inch filters.

11) Collect the constraints on the imager port - mass, size, torque (Claver) Done -- see report of Feb 2001 telecon (WIYN can support ~800 pounds) .

12) Identify the roadblocks and speed bumps that may delay a 2-CCD OT camera (Tonry) Done -- problem getting packaging material is delaying delivery of CCDs. Still hoping for tests in the late summer.

13) Maintain pressure on WIY departments and administrators to hire instrumentation-capable scientists for WIYN (Jacoby, possibly during visit #2 in February) Done -- some response from the departments (Jay Gallagher is leading the science effort and several department members are helping Jay, Bill van Altena volunteered to help with astrometry)

14) Develop arguments for hiring an opto-mechanical designer for WIYN for 1 year (Jacoby, Green, Claver)

15) Alternative to above - identify a scientist/manager at Wisconsin who can supervise a PSL engineer (Gallagher) Done -- not possible

16) Determine if silver coatings can be applied to mirrors at KPNO (Claver)

17) Measure the image quality at I and Z, perhaps with FastTrack (Claver) ; or use the Yale speckle camera if we can get it out for a day or two prior to a run.

18) Assess the reaction of NSF to ODI relative to other wide-field imagers (Jacoby) Done -- The key to ODI is viewed as the detector developments as a pathfinder to LSST.

19) What is the comfort level at the NSF for a grant to a 3.5-m telescope (Jacoby) Done -- NSF felt that continued investment in maintaining critical 4-m class telescopes is not an issue.

20) What is the maximum FOV (with and without vignetting) at WIYN (Claver)

21) Evaluate PSL's schedule for doing conceptual design work (Gallagher)

22) Probe vendors (Rockwell, Lincoln) for level of interest in hybrid mosaic concept (Tonry) Done -- Lincoln is very interested is working with the ODI Team. See April 2001 trip report to MIT LL.

23) Review controllers and their applicability to ODI (Starr) Done -- Barry is involved in a detailed review of controller issues for NOAO, as well. He and Barry Burke of MITLL will develop the electronics concepts for ODI.

24) Set up ODI web page for those involved, complete with bibliography of technical papers (Jacoby) Done -- see http://www.noao.edu/wiyn/director/odi
