    You were right on the "BrDigMultTile" - it's changed. However, it
    still isn't what I'm looking for. The mapping, you say, from detector
    to entry in table, is via the subscript in the table. Well that's
    fine, except the subscript is a loop parameter. Hence, at least it
    looks that way in the code, the number of subscripts may change from
    event to event. How then, can one be sure that the mapping is unique
    and constant? Have I missed a point here? Is it so that each and every
    channel is read out with 
    
      fRawEvent->getRecordMappedAdcBlk(kMultSI,mapped_adc_blk_hits,nhits);
    
    even the ones with zeros, meaning that "nhits" is really a constant
    (164)? If this is the case I get your point, but then I really don't
    see the point of some of these variables, but hey, that's just me
    babling.  
    
    I'd still like to know how to map the 164 indicies into actual
    detectors though. How do I fins this mapping out? Is it somewhere on
    the web? 
    
    Thanks Kris.   
    
    Cheers,
