The attached plots show the time-stamp data in the EURICA files with PID information (EventInfo.timestamp). The
timestamp value should correspond to the correlation scaler included as info_code==8 in AIDA. 

The plots show time-stamp vs entry number in the TTree of the Root file, with the events in groups of about 10
*.root files counted consecutively. To map entry-number to data file use informatino of number of entries per
file in the lines bellow (output of analysis script). NOTE: label for plots in right colume is wrong, trigger
type=3 (pulser) in stead of 2.

The final three plots (pulser_dts_go4_3022*.png) show the time difference between two sequential data points of a
given trigger type (fBit==2 or 3). The value that would correspond to the external scaler (fBit==3) has a peak at
about delta(ts)= 1.7 sec, but also a lot of events with a distribution centered around a smaller value of
delta(ts)~ 10 msec! One can also see the deadtime at about 300 usec at a smaller scale. The units for the
time-stamp are 1-ns.

A plot of a similar distribution for the data in AIDA shows that the peak of the correlation scaler has, in this
case, a very narrow distribution, with a frequency of ~43.5e6 x 40 ns (would agree with Go4 data from EURICA).

When scanning the files the analysis script (attached) skips a given number of entries (~100) to speed up the
analysis.
