Bonn VPTT subunit cosmics setup:

• Plot of shaper-included measurement shown by Tobias
• The absolute values need correction factors due to impedance mismatches and/or choosen shaper gain ranges
• Looks like "preamp-only", "shaper-included" and "earlier oscilloscope" measurements from Bonn will give consistent results with cosmics
• However, the beam data results from last year's Bonn beam time significantly differ
• Difference may come from shaper: at beam time we had to use the low gain, with cosmics the high gain branch
• Agreed to end this cosmics data taking at Bonn
