explanations for cuts used: 

control: 
++++++++
  for double mode: mumu / ee / emu: (di-Lepton triggers)
                         18: corresponding trigger mode is not active
                         19: corresponding trigger mode is activated
  for single mode: hipt_mu / hipt_e: (single hi_pt el or mu tracks required)
                         2: corresponding trigger mode is not active
                         3: corresponding trigger mode is activated

pt:
+++
  pt cut in GeV for the SLT-track found;
  pt of track has to be above

mass:
+++++
  cut on the invariant mass of the trigger pair
  has to be above

ip_low:
+++++++
  distance cut, distance between the two track candidates;
  distance has to be above

----> the other cuts are not used any more, since the database would have
      to be changed, the definition of the table has been kept
