52	52	* After starting, the stop button appears only after saving abut 200 shots to prevent too early stopping which may disturb the DAQ.
53	53	* Each run has a unique run number. This number is needed to retrieve the data later on. So it is important to keep track which number is associated to what experimental parameters. Note that the run numbers are used by all FLASH DAQs (currently about 10). It might thus well be, that two consecutive runs from you do have run numbers which are spaced by more than one if another DAQ has been started in-between ...

It has in addition simple analysis options like histogram, mean, min or max values as function of time etc. Also correlations between different parameters can be analyzed in the tool.
