BPMs which didn’t work after shutdown
4
Aperture scan analysis: offline to online *Comparison has to be done with two software.
5
Aperture (90%) before and after shutdown Long Short * Assuming beam size was same. *Central position from the data after shutdown was normalized to the data before.

Aperture: Upper - Lower
