    There should be         PID(firstplate) always 1

    There is a difference between the pid of the EdbPatternsVolume and the PID() of
    the segment couples,
    but at the point where the EdbPatternsVolume is read in, the information on the
    PID() of s.ePID is overwritten.
    Example: Basetracks of 01.cp.root have s.ePID==1 for Sim Basetracks
    after reading in, here they have  pid= 10
 
    For our simulated data this has alrady written in at reconstruction level:
    segments of 01_001.cp.root have PID()==1                (z==0)
    segments of 56_001.cp.root have PID()==56               (Z==71200)
    segments of 57_001.cp.root have PID()==57               (Z==72500) [but pl 57 not existing in simulation]
    But for data from BG scannings this is arbitrarily (mostly zero)
    So we set this automatically here:
