TMSY freed (Corey, Keita)
After SUS team was gone, we went in the BSC10 to check a potential rubbing issue that has been bothering SEI.
After backing off all EQ stops and making sure that the top mass is free, we've found that the top mass had ROLL tilt, and somewhat smaller PIT. We don't know where this came from, but in my experience TMS angle changes after transporting to the chamber.
We corrected the roll and PIT by moving top balance masses, roughly centered all BOSEMs (the only one that was left untouched is RT) and left it damped.
Note: While working with TMS yesterday, noticed that the TMS cartoon at the bottom left of the TMS screen (SUS_CUST_TMTS_OVERVIEW.adl) is backwards. The Side, F2, and Left BOSEMs are on the "front" end of the TMS. (Once I get better with medm-editing I can fix this.)
