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.

151 151  * pre and post peak integration time: how much ns to be integrated before and after the peak sample that are taken into account for the peak
152 152  * pre and post peak noise time: before and after the samples that are taken for the actual signal these samples are used as background ( they also can be used to define the "deadtime" of the detector before it searches for new peaks.
