BSC06 ETMy Pitch/Yaw Alignment Check
D. Cook, J. Oberling
We set our equipment back up and measured pitch and yaw of the ETMy this afternoon. The results are as follows:
-
Pitch: 850 µrad down
- Desired is 639 ± 160 µrad down, therefore this is out of spec
-
Yaw: 220 µrad CCW
- Desired is 0 ± 160 µrad, therefore this is out of spec
As can be seen by these results, further adjustment is necessary to bring the ETMy pointing into spec.
