Dear all,

next week Monday and Tuesday is close and i think we need an agenda for
the meeting. Following the developments and efforts in the last weeks,
I think an agenda should look roughly like this.

1. pi0 reconstruction in the calorimeters         Monday morning / early afternoon

   FCAL status of simulation and reconstruction of photons/pi0  Mihajlo
   BCAL
   status of simulation and reconstruction of photons/pi0  George/Zisis
   analysis of test beam data                              George/Zisis
   analysis of cosmic data                                 Christina

2. TOF                                            Monday afternoon
   -- tof wall                                             Matt/Beni
      status of simulation and test beam measurements
      what momentum resolution do we need, plans

  -- Bcal
     analysis of test beam data                            Blake

Tuesday morning

3. what does the new material in the FCs do to shower reconstruction      Richard

4. Kaon identification                                     Eugene
   --- what does a cerenkov or a rich give us
   --- do we need Kaon identification in the non-forward regime
   --- what will kinematic fitting and strangeness conservation help us

Discussions:

5. What needs/can be done till the calorimeter July meeting

6. when are we ready for a PID review


I know I have assigned people as speakers without asking, this are only
suggestions, of course things can be changed. Just complain to me and I
will update things.

cheers elke
