• Spent most of this week digging through millipede
• Looking at extracting information from MAUS data structure and feeding it into the millipede software
  • Trying to get straight tracks from the trackers
  • Rogers mentions air between the trackers; and potentially anomalous scattering results of 50 mrad RMS from Chris Hunt analysis
• Interface to millipede is flat ROOT tree; space point where the track starts and gradient
  • Fodder is angle and a position at the TRP
  • Millipede has internal clustering and patt rec algorithm which is incorrect
  • Not sure if millipede allows material between tracks/planes
• Remnant fields; simulation run but not analysed

• No update, moving house

• Residuals plot
  • pt residuals look like they should do
  • pz offset was incorrect reconstruction by tracker
• Looked at pt correlation with pz; no real help
