comments:

• RF phase modulation parameters change, excitation amplitude increased to 0.6 deg to be above threshold. minimum bunch length to 1.22 ns. longitudinal q factor much lower with new excitation

• ATLAS wrong lumi published at the end of adjust by a factor of 3, fixed at the start of SB

• 10h lifetime when going to collisions

• spike in IP2 luminosity before the beta* leveling at 56 cm due to sudden jump of B2H DOROS orbit due to bad BPM reading

• tune optimizations with wire on, increasing horizontal tune for beam 1 was beneficial

• went back to adjust at the end of the fill and moved out jaw of TCSG
