Andreas presented the report from the algorithm review. Marek. The MUON resolution is too good, but probably the reason is that the fluctuations of the gas gain are not taken into account. It leads to an additional factor of Sqrt(2). PG. Simulation of SPD:The timing error was introduced and the comparison with the test beam date is better. The work is going on. Boris. SSD double peak problem - the double peak is seen also in the test beam data. Qualitatively the pictures are similar. It probably is related to the low energy electrons. The effect is also presented in the pixels. There it is masked by the low number of double clusters. Is the neutron capture in Xe put in the TRD simulation? The effect is less then 5% and there is a person working on the simulation.
