Before engaging in a time-expensive analysis please realize
that since friday

_ R10bottom (tof scint) was not connected. too bad.
_ R9bottom (tof scint) was connected to the cables of R10.. too bad

* we had to disconnect cables in order to put mu-metal shields, and
* the above clearly escaped the friday afternoon check by tavi
* but if you noticed that on shift, you could have called me and we/you
* could have gone down into the hall. It'd have been plain to see

_ The above "bug" results in not having a full data sets for L/R
  asymmetry. All data since wednsday -> friday morning is good and should
  be enough.

_ It also means that for the efficiency of CC-R2 we can only use tof
  # 8. Too bad.. Rtof9-10 are the central ones behind CC-R2. For
  consistency, you may want to take a look at the eff of CC-L2 using #8,
  since the geometrical inefficiency should be the same L/R

more to follow
