Thanks a lot for the feedback, Marco!
I have found out that runs 6333, 6337,6339, 6341 have no CCDB entry for
the RF offsets. I had ran the RF calibration routine over all runs that
had been cooked and filtered, so I guess these 4 runs were not included in
either the cooking or the RF filtering of the previous pass.
Zhiwen and Aram, can you please produce RF filters for these runs so that
I can calibrate them?
Thank you!
Best regards,
Silvia
> Dear Silvia,
> I have completed the study of the RICH timing by looking at the

> the real check can be done only by looking at the full runs.
> - for runs from 6189 to 6399 the shift is about 11 ns
> - for run 6386 the shift is about 13 ns
> - run 6293 has all the histograms empty, It seems this run has empty
> histograms also for other detectors.
> - runs 6333, 6337,6339, 6341 have two peaks, indicating an RF correction

> cooking v15.
> I have updated the last Friday meeting wiki page with all the plots.
