Hi Martin,
Soon a commit should appear (i sent out a patch) for $AliPhysics/PWGPP/EVCHAR/FlowVectorCorrections/
where I added an example task QnCorrectionsInterface/AliAnalysisTaskQnAnalysis that shows how to take the Q-vectors from the correction framework.
The way it's currently organized is that the Q-vectors are passed using an exchange container, you'll see the setup for this in the accompanying macro QnCorrectionsInterface/macros/AddTask_qnanalysis.C
To come to the question in your last email, the file containing the necessary calibration histograms can be added in AddTask_ep.C (l.94) (you can also produce such a file using this task). Currently it points to a calibration
file for LHC10h that I have in my alien directory. I think this should work also for you, I tested it for myself.
I hope this can get you started. Btw I tested this for ESD analysis, AOD might require some additions. In case of you have questions or problems please let me know.
Cheers,
Jaap
