      NIRO align
0:46   ???   /-1800
       recording at 500Hz/DEST
       the beginning of the file has only W1W2, as we were waiting for delay on the other baselines
       then we have all 3 (nice) fringes

       lost tip/tilt on E1 at some point, shutter sequence should not be affected (but will need to compare with first shutter sequence which was definitively not affected)

     2T ONLY, W1W2, though we scanned around for fringes
     lost B1 (E1) and B2 before the end shutter sequence 
     Use only the starting shutter sequence anyway
