+S4 GEOMETRY UPDATED:
+The x and y dimensions have been corrected because they were wrong.
+A container of aluminum has been added having walls of thickness equal 
+to 0.1 cm.   
+
+TOF POSITIONS DEFINITELY UPDATED:
+S2 and S1 have been positioned again, after the simulation of the top plate.
+Before now, the positions were put ad hoc 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.
+
+ND GEOMETRY COMPLETED.
+The He3 and the polyethylene (CH2) have been added to fill
+the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
+details of these materials.
+
+TOP PLATE GEOMETRY ADDED.
+The top plate geometry has been simulated as a N2 box that has the same
+dimensions of CATA. Inside it, at the right positions, there are S2 and CATA.
+The real top plate is a rectangular window having a thickness of 0.5 cm
+(volume TPTL emptied by the volume TPCV). This volume is filled with a mixture 
+of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium
+are the four volumes TPTU, which are positioned at the corners of TPTL at the
+same height of CATA, and the four volumes TPTM, which are positioned at the
+corners of TPTL, at the same height of S2. 
+The geometry  of the top plate is based on a simplified version of the CAD
+drawings. 
+
+October 2006, Bari
+
+The geometry of the neutron detector has been updated. Some dimensions of some
+volumes have been corrected and the aluminum cover and the aluminum boxes to
+put the cables have been added. A new material, the cadmium, has been also
+defined.
+
+September 2006, Bari
+
+SPHE and ND data card bugs fixed: the definition of the ND data card,
+missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
+data card has been changed. Before the correction the data card:
+NDET 'SPHE' was used to delete the spherical top shell to substitute it with
+a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.

 The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
 and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
