Mirror positions and beam position on the imagers for 14.8 keV SPB, 2mrad
ATTENTION: the alignment was difficult due to the strong background from SA3 with 500 pulses. For the future, maybe SA3 could reduce to single pulse during alignment of SA1. This would make the process easier.

fig6: for comparison, this is the M2 popin image when a strong background from SASE3 is coming (500 pulses, 3milliJoule, 2.1 keV)
