Subject:	K2 eng time request
Hi Hien,

I have a request for K2 eng time using OSIRIS-NGS

1. PI: J. Lyke, Co-I: Randy Campbell
2. K-band 100 mas background measurement (performance of new pupils)
3. No test number
4. 0.5 nights request
5. We will measure sky background in both the old and new K-band filters to see the effect of the new 100 mas pupils.  Remaining time will measure standard stars in various modes to determine OSIRIS sensitivities.
6. K2, tertiary mirror installed, OSIRIS in AO (must avoid IF runs)
7. We will use the OSIRIS DRP to produce data cubes and extract the spectra.  Backgrounds and sensitivities will be posted on the OSIRIS web page.
8. Prefer June 05.  Prefer to avoid June 19-20 due to heavy support load and June 19 is my birthday.
9. No status on this engineering (new instrument capability)
