    Hi Flemming and others,
    
    Flemming, before I commit my work, I'd like to tell you a bit about my
    changes in gbrahms:
    as I wanted to get a feeling of how my PID stuff worked with the MRS
    arm,
    I 've changed the TOFW geometry setup, but more deeply than what I told
    you
    in previous emails.
    I understood the spirit of your setup but then, I faced some problems,
    still because of a unique
    name you assign to several different volumes. To make things working for
    me, I simply replaced
    tofw_no_panel_types   by   tof_no_panels and made the needed changes in
    function of that
    (in src/mids/bd_tofw.F, eg_tofw.F,  inc/geo_tofw.inc and finally
    user/write_geom_defs.F)
    
    What I have now is 4 panels called TFP1, TFP2, TFP3, TFP4 each of them
    containing 21 slats
    (TFT1 for TFP1, TFT2 for TFP2 and so on).
    I know that this is not the original idea and if people don't want to
    follow mine then they're
    invited to make the necessary changes to respect the original scheme,
    but my version of gbrahms
    works fine, I get hits correctly and I 've made the corresponding
    changes in gbr2c.f for the cdat file.
    I can now digitize, process a PID  and so on for TOFW and MRS arm .
    At this stage, the parameters of these 4 panels in
    DetectorParameters.txt are just a copy
    of those of H1 and H2. We therefore need some new sets of parameters for
    future analyses.
    
    Now, I'd like to get your opinion (and from others too if they like)
    before commiting all that stuff
    (if you agree, I'll do it tomorrow).
    
    Thanks
    Djamel
