Timewalk and drift time correction
• Each Row is normalised to its peak value• If the first 2 (or more) hits have the same
timestamp, I take the next to highest ToTvalue as the ToT of the second hit
• Entry- and exit-pixel distributions clearly visible
Needs timewalk- and drift-time correction
Only needs timewalk correction

• Only select clusters of three with hits in the top two pixels of a super pixel
• Top two pixels of a super pixel must have equal ToA and fToA
• Third hit must have ToT == 1
• Only select clusters of two with hits in the top two pixels of a super pixel
• Top two pixels of a super pixel must have equal ToA and fToA
Non-uniform ftoa distribution
