During the work, we found the strange(?) calibration-factor unbalance of MCI and MCE OpLevs (see attached).
The difference between PIT and YAW calibration factors are about 20 and 3, respectively.

If the beam profile is not so eliptic, the calibration factors should be almost same for both PIT and YAW because the incident angle is small for MCI and MCE.
It would be necessary to check the beam pofile of both OpLevs.
