WTTM

WIYN's role in completing WTTM - more active.  

Assumed responsibility for 

	getting manual

	obtaining filters (has purchased Sloan set, Johnson)

	scientific commissioning roles (Kent, Chuck, Abi).

	procure science grade CCD - remains NOAO's responsibility
		Dave S has been working on monsoon controllers, and we
                may be able to run new detector over the summer.

	WIYN had agreed to support project at 1.1 FTE level - this has been
		continuing to an additional year

Priorities indicated as H, M, L
	1. produce observing manual  --  Pat, Charles, Chuck (in progress)

	2. DIQ improvement estimates at various filters 
                -- WTTM with and w/out correction (BVRIZ, but they are only
                   doing B, I)
	        -- compare with mini-mo as baseline (static vs. static)
	        -- also effective throughput
	        -- dependence with guide star mag/correction speed, distance from
                   guide, mean seeing evaluation in B and I
		-- PSF variation across field
	3. distortion map (March T&E) -- must be in header

	4. wavelength response characterization w/ each dichroic
	        -- we have beamsplitters in hand; Chuck signed off on
                   backside AR coating
		-- frontside coatings supposed to be delivered on 15th
		-- don't have vendor for R beamsplitter
		-- ordered 2 8515 beamsplitters

	5. CCD response properties: linearity, fat-zero, noise-isolation, 
	   cross-talk (part is March T&E)

	6. shutter characterization: timing correction and shanding correction

	7. image and optical alignment of both IAS mount and pickoff-mirror

	8. scattered light measurements

	1. verify accuracy and completeness of header info (to within limits
           Charles has)
		-- does ccdproc work

	1. does focus tracking work?  focus error sensor reading as a function
           of telescope out of focus -- want to show that the error sensor is
           capable of responding to defocus in all the filters.
	2. does instrument 'talk' correctly to WIYN control system? done

        3. DADS connection - done

        1. focus offset with respect to minimo -- not planned for this T&E

	2. do flat fields work even after switching

	1. Interface to observer will streamline command structure at this T&E
		observer has a primer on what all this telemetry means
		have Kent write a summary of what improvements needs to be made
		need functional interface plus primer

	1. photometry demonstration

	1. throughput 50% with the 95/5

        observers need to know if there is a chance that they'll want to use
        WTTM to put that in the ORP.

	tabled discussion of whether just to accept WTTM with the caveat that
	NOAO still has to deliver red-sensitive camera vs not accepting until
	camera is delivered

	tabled discussion to boost WTTM scientific productivity

	what flexibility do we require in scheduling
