Hi Dieter et. al.
Let me just comment to one aspect in your e-mail.
It is fair to say we do not have enough pp data from the brief run in
January. Some of the angle
field settings did not have good inel-counters setup, I recall some of the
90 deg settings in particular.
On the other hand many other settings should be quite reasonable in quality.
Though analysis is in progress
this has not been completed so there is not a good answer to your question.
The data one would need to
complete the pp comparisons is probably only at most 2-3 weeks worths of
running, and thus raises the
scheduling issue; should this be requested if it in fact takes out 2+3 (for
beam switching +setup) weeks
before one can get this?
Your comments on the need for AuAu running in run-4 should certainly also be
included. I would prefer doing it as a
possibility since it is not yet worked out.
