Here the complete bunch train from the FEL is recorded (FLASH1 and FLASH2 pulses). Thus there are values from FLASH 1 in the first part. they may be separated by several "0" values if the reprate is different from 1 MHz ...   - It shows a very good correlation to the arrival time  of the XUV pulses in the experiment (see help).
++units: fs (bigger numbers (typically) indicate later arrival times of the electrons).
