Thus the first bunch of FLASH 1 comes at "700" and the last possibel bunch comes at 1300 (700+600). After FLASH1 train is over ther is a about 70µs switching time with no bunches. Then comes the first FLASH2 bunch.  Thus if e.g. the start time of FLASH2 is 1200 it means that FLASH2 starts at column 500 (1200-700)  in the HDF5 files. (However for yet unknown reasons this may change by 2-3 colums ...)
