Hi-lo settings for CD22 flights

Testing the 3 HIGH_LOW settings for 03_0126 (Lee).

Summary: A similar setup for all three settings:

1. Slit6 (3.2")
2. Echelle order +2
3. 14-pix BP13465
4. Filter: OPEN

On the 260K blackbody, N0 D0 will work without issue (<3000 ADU).
The GUI setup in Waveno0 has an angular offset -- to get the WN you want at the center of the detector offset the waveno entered in the GUI by -5.6 cm-1.

Setting 1: 756.9cm-1, 2nd order, HIGH-LOW

Instrument Setup: Slit 6 (3.2"), 14-pix decker dash BP13465, FILTER=OPEN, EDEG=22.5611 degrees
On room: OT= N0 D0 T0, Frametime=1.0s

The waveno0 is off by about 5.6cm-1. We will have to adjust to best setting.
flux(room)/flux(260 K) ~ 1.6. Therefore, ND pairs on the blackbody will be comfortably below 3000 ADU.

756.9 cm-1, 2nd order, gas cell spectrum;
Real waveno0 appears to be ~ 762.56 cm-1

Setting 2: 768.5 cm-1, 2nd order, HIGH-LOW

Instrument Setup: Slit 6 (3.2"), 14-pix dash BP13465, Filter" OPEN, EDEG= 22.1781 degrees

On room: OT= N0 D0 T0, Frametime=1.0s 

The waveno0 is off by about ~6 cm-1. We will have to adjust to best setting.

flux(room)/flux(260 K) ~ 1.65. Therefore, ND pairs on the blackbody will be comfortably below 3000 ADU. 

768.5 cm-1, 2nd order, gas cell spectrum;
Real waveno0 appears to be ~ 774.xx cm-1

Setting 3: 745.6 cm-1, 2nd order, HIGH-LOW

Instrument Setup: Slit 6 (3.2"), 14-pix dash BP13465, Filter" OPEN, EDEG= 22.9468 degrees
On room: OT= N0 D0 T0, Frametime=1.0s

The waveno0 is off by about ~6 cm-1. We will have to adjust to best setting.

flux(room)/flux(260 K) ~ 1.65. Therefore, ND pairs on the blackbody will be comfortably below 3000 ADU.
