To clarify,

This is in addition to May 17.  The plan for May 17 will be determined in a meeting on Monday, 21 April.

Hi Hien,

I'm proposing for 1 additional night for NIRSPEC/MAGIQ engineering

1. PI: J. Lyke, Co-I: S. Panteleev, S. Kwok, J. Johnson
2. Purpose: Continue MAGIQ software and optics tests, specifically image quality measurement, and additional guiding modes
3. No test number
4. 1 night total, may be broken into 2 x 0.5 nights
5. Guider images will be recorded with the IQ element in the guider beam.  We will send known piston and tilts to the secondary and measure their effect on the IQ images.  Offset guiding on SCAM with the rotator in stationary mode will be tested.
6. K2, tertiary mirror installed, NIRSPEC on RNAS
7. IQ images will be analyzed by S. Panteleev, guiding performance will be analyzed by J. Lyke.  Procedures for night time operation will be developed and presented to the OAs
8. Prefer June 24 or after
9. Previous MAGIQ engineering time has allowed us to release MAGIQ for science operations on NIRSPEC.
