Laszlo | General | misalignment in the pattern | 2021 |
for some reason the event number of the target ON and OFF was misaligned with the pattern.
This means that the last few runs (run53, run52...) measured not in the target on phase but one before (at 10 instead of 11). Therefore, with these
runs we measured the TargetOFF phase instead TargetON (that is why the pg peak seem to disappear...) |

For a few minutes there were no particles in SIS.
