For the time being we can summarize the discussion in two points : \r\n\r\n- Weight matrix formalism for the Kalman Filter.\r\n- Trials to reduce computations in some steps of the reconstruction.\r\n\r\nIt seems to me this can nicely fit in the Event Model. The way I see it he could share with us his thoughts in a // session. @betatim @GerhardRaven @manuelschiller Thoughts ? \r\n\r\n"}}
