17/Apr/2001: We have already constructed a prototype of the tool and started to implement the SMT information on Primary Vertex (PV). We use the method "L3TPrVtx::getVtxProbs()" that returns a vector with the probabilities of each PV found.

28/Nov/2001: Multiple primary vertex rejection fully implemented. The desired value of the probability of occurrence of multiple primary vertices, above which the event is to be rejected, will be determined from Monte Carlo studies

17/Apr/2001: We intend to use the information of the Calorimeter unpacking to obtain the energy deposited in the direction of the diffracted hadron (proton or antiproton). We will determine the specific region and energy cut to optimize the use of the Calorimeter information. We have tried to talk with several people (Leslie Groer, Mrinmoy Bhattacharjee, Volker Buscher) from Calorimeter to discuss which would be the best method to be used. Now we are waiting for the feedback from Lee Sawyer.

28/Nov/2001: Maximum longitudinal energy cut implemented. The maximum longitudinal energy avaiable for the reaction is evaluated using information from FPD track reconstruction tool (l3ftrack_fpd), and is compared with the total longitudinal energy deposited within a cone around the beam pipe. The parameter defining the optimum cone overture will be determined from Monte Carlo studies.

17/Apr/2001: We have discussed with Mike Begel and we had a video conference with Chyi-Chang Miao. They are trying to finish the hardware and electronics. They believe that the on-line tools should be ready be June or July. They will be able to provide information both on average time and multiplicity at North and South hemisphere.
