    Christian,
    It seems as if you are looking at an old version of BrRawDataInput.  All
    of the BrDigMultTile stuff is commented out and will be removed entirely
    shortly.  There is now a BrDigTiles which contains an array for all of the
    ADC's.  They are no longer put into a table.  The BrDigMultSi does set the
    id in the version I have.  That is kind of redundant at the moment,
    because all ADC's of all Mult detectors are read in each event as far as I
    know now.  So the id would be directly related to the hit number.  Same
    for the BrDigTiles.  The identity of the detector is known by which entry
    it is in the array (fAdc[]) in BrDigTiles.
    
    These changes were made some time ago, so they are surely checked in.
    
    Hope this helps
    
    Kris
