81 - ~* note that the sample rate is NOT locked to the FLASH repetition rate ! Thus there is a not integer number of samples between FLASH pulses. The sample rate also differs slightly from ADC card  to ADC card. The rough spacing is **1993.846** samples between 2 pulses at 1 MHz for details ask the local contact.
