We decided to quickly take OLTFs for the ITM R0 stages since we didn't have any yet.

Note: These measurements were taken with the 0.4:10 (old) satamp

ITMY R0
- Measurements taken with suspension in HEALTH_CHECK but with damping loops on
    - optic align offsets off, L2->R0 damping off, etc
- We needed to lower the excitation amplitude for V (10 -> 2.5) and Y(300 -> 10) to keep the suspension dac from overflowing and saturating. In the case of V, we could get full measurements with the excitation amplitude at 5, but the coherence was poor, so I lowered the amplitude to 2.5 and that worked to make sure the osems weren't being overdriven. These excitation filters were originally matches to the ETM R0 ones, but we had to adjust them.
