Analysis software wishlist from May 2020 CM

Event Generation

• have flat mass generation be actually flat (currently increases at high mass in many channels) - fixed, pull request from Alex A.: [1]
• correctly handle unstable particles at the lower vertex
• correctly throw events flat in angles, like in omega pi system
• consistent plan for handling different models of t-dependency

Amplitude Analysis

• Standard way of generating flat trees from DSelector output
  • ROOT scripts?
  • Update and generalize tree_to_amptools?
    • Benchmark against analysis launch?
  • New AmpTools data reader?
  • DSelector flat tree output?
  • Look at FlattenFSRoot and adapt data reader?
• Slice up data and perform different fits
  • bins of mass
  • bins of t
  • different wave sets
  • different starting parameters
  • resampling for bootstrap error estimation
• Output format
  • text files?
  • SQLite DB?
• Plotting
  • Generic GUI program?
  • command line program?
  • easy interface to results based on different fit variations
  • visualize both amplitudes and comparison between data and weighted MC
• Common routines/procedures for error propagation
