8R Steering to Clean Up 9L

Log Number: 4186981Logbook(s): Entry Makers: bjacobBody: 

We started to get 9S00 BLM trips and the crew chief correctly identified that the 9L orbit was getting ugly (I failed to capture pictures, My apologies). I used the magnets shown below to bring in the orbit and the 9S00 signal looks a lot better now.

Gang Phase and Pathlength Measurement and Correction

Log Number: 4186974Logbook(s): Entry Makers: emonkBody: 

Started by establishing about 5uA of tune beam to the 2R02 to conduct gang phase corrections. Gang phase was manually adjusted using SLMs and the tune mode camera setting. After initial gang phase corrections – the Dogleg Calc12 application was run in (modified) accordance with the (Pathlength Measurement and Correction Procedure).
