The QE measurement earlier this morning, before the orbit shift, showed much lower QE than anticipated. After changing the orbit around IPM1I07.XPOS, the OPS did a second QE measurement and now the QE values are fine.

With the new orbit the PCup is collecting more (all) of the beam current, indicating something was not right with the orbit during the first QE measurement and beam was not centered on the cup.
