+
+NEW ANTIPROTON ANNICHILATION CROSS SECTION
+
+   The new cross section has been added by Sergio Bottai to the geisha code.

+NEW TAGGED VERSION: v4r8
+
+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

 The x and y dimensions have been corrected because they were wrong.

 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

-corners of TPTL, at the same height of S2.
