Jason, Kiwamu,
We revisted the calibration of the oplev on ETMX and ETMY which showed calibration error of a factor of a few (alog 18218). In fact, they alll had underestimated the suspension angle by roughtly a factor of two. Here is a summary table of the calibration factors:
old calibration [urad/cnts] | new calibration [urad/cnts] | |
ETMX PIT | 81.2 | 222.5 |
ETMX YAW | 115.2 | 263.4 |
ETMY PIT | 77.94 | 172.2 |
ETMY YAW | 53.55 | 115.4 |
We also updated the SDF so that these new values are already reflected. Note that the number I updated yesterday was not accurate enough (alog 18218) since I was using the misaligned ETMX. We calibrated it again with the aligned suspension. I attach the measurement data nad fitting codes as a zip file.
