This is the first public push of the 19O(d,p)20O analysis code, but this experiment was analysed several years ago by Dr. Irene Zanon, producing:
  -- I. Zanon, Ph.D. thesis, Università degli Studi di Ferrara (2022)
  -- I. Zanon et al., Phys. Rev. Lett. 131, 262501 (2023)

The original IZ Analysis.* codes are available elsewhere.
