NIRC2 engineering, photometric calibration.

1) J,,H,K,Lp,Ms photometry, 2 cameras,2 pupils, DM open, TT Closed. Use various standard stars over a range of airmass

2) Photometric comparison between cameras. K band, insc pupil, AO off. Take series of nod 5 5 snapi's in all three cameras, going up and down the camera slider twice (e.g. W-N-N-W-W-N - note order, the N camera is in the middle!).

K2-AO tests will be interleaved with NIRC2 tests

Objectives:
- Verify that the DM and TT loops are decoupled.
- Investigate if changing the controller improves things.
- Obtain the best possible Strehl on a bright star.
- Find the magnitude of the noise and bandwidth error terms.
- Compare the 1.0” plate scale.

Choose a bright star (V=6) near zenith.
Reconstructor: Bayesian,
