+ BUG FIXED
+    For some reason there was a conflict using FLUKA and the GARFILD
+    interface for the TRD. The file TRD_ATT.TXT was treated as flukaerr
+    file by the compiler. It is not clear why. The code was correct,
+    the logical units and names were not inconflict, but the compiler
+    assigned to them the same internal number. It may be a problem
+    related to the optimization phase. I did close the file just after
+    the read-out in GPDAT.F and commented out the closing in UGLAST.F

  TOF POSITIONS DEFINITELY UPDATED:
  S2 and S1 have been positioned again, after the simulation of the top plate.

+ Before now, the positions were put by hand based on the positions given by
  Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
  sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
  S. Ricciarini on the 20th of December 2005.. These positions were

+ lightly approximated because the thicknesses of the mylar and of the glue were

  ND GEOMETRY COMPLETED.
