to a single root file for each measurement.
It is very important to highlight that sometimes

  273   Wed Apr 8 20:06:10 2020 LaszloCalibrationCounts in the K-REC peaks 3 datasets were investigated:
-124Xe with Scraper    (2. Xray calibration
parameters needed)

  272   Mon Apr 6 23:00:51 2020 LaszloCalibrationbeam energies for 124Xe and 118Te measurements "The e- cooler settings were the same for
the 124Xe and 118Te beams" - Sergey --> speed
of the ions is the same --> same MeV/u
