--(1)  Faint Limit (conditions permitting: ~3/4" seeing and clear)
Time required - about 1 hour
Task:  Use NOMAD database to obtain stars of known R/J magnitudes and coordinates.  NOMAD works best here due to information available at the fainter limits.
Measure count rates with star magnitude range  10 - 17 Rmag
Get at least 12-15 points, push to faint limit, develop plot/graph/formula



--(2)  Explore practical 'slow' limit of ACQ/Correction frequency for WTTM guiding.  (0.9 arcsec seeing or better, more or less clear)
1-2 hrs.

Right now, has been shown to be about 40 hz below which, fwhm gains are small to none depending on conditions.  Being able to keep and hold guiding at slower acq rate has tradeoffs with improved FWHM and gain settings.

Operationally, WTTM uses slower Acq rates to increase S/N, outlined in OA guide for WTTM.  Ideally, one wants to guide at 100 hz or better.




--(3)  Examine Focus error sensor signal and telescope defocus.  (Must have good seeing)
2 - 3 hrs

(a)  signal still present with DIQ issues ?
(b)  measure defocus vs error signal curve/relationship (dependent on seeing)  This could be very difficult as telescope focus is constantly changing so, expect this to be several efforts to confirm or improve upon initial results
(c)  Determine focus error signal zero point relative to say, J-band in-focus images with WHIRC.  THIS MAYBE the 'killer' in being able to use the focus error signal.
(d)  Use b & c to give OA a 'guide' for correcting focus assuming 'a' above is favorable.
(e)  Re-learn use of focus correction software  (gui does not implement this correctly, only has the data entry windows)



--(4)  Test update to WTTM interfaces for new scale factors.
~ 1/2 hr
