Test of pytorch version and our python RAAR version reveals differences for experimental test set. Found three differences in code:

  • RAAR (pytorch) returns object not yet filtered by support
  • last iteration of pure error reduction iterations are missing
  • most important: in the pytorch version, the support is defined and applied for real AND imaginary space.
