Attached is a comparrison of how the OSEMs for ETMX, ETMY, ITMX, and ITMY changed from before the Montana EQ to after.

The OSEM sets (for example, pitch, all stages) are color coded:

• green = sets that are reasonable, which means no sign flips, and numbers are largest at the bottom stage
• yellow= sets that have a sign flips, but all OSEM values are small, and changes are small
• red = sets that have sign flips and have large changes in OSEM values between stages

Just looking at color, ETMX and ITMY are all yellow or red (more likely to have had issues as a result of the EQ?), and only ETMY and ITMX are green and yellow.
