To be used by experts only.
Monte-Carlo only: for datasets produced with JULIA 306 and after, the TPC hits are smeared to better reproduce the data. The track banks FRFT/0 and FRFT/2 contain the parameters of the tracks fitted from the smeared hits and are transmitted to ALPHA variables.
If the data card FR12 (resp. FR10) is given, the ALPHA variables are filled with parameters of tracks fitted from unsmeared hits with (resp. without) VDET. This allows to make some comparisons w.r.t the smeared hits.
FR10 or FR12 is not compatible with FRF0. Cannot work on MINIs.
