+The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
+and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
+nominal height as measured in PAMELA (See the document: "Main geometrical
+parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
+E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
+of S21Y and S12X are higher than those in the cited document due to the fact
+that in GPAMELA the thickness of the mylar has been considered while in the
+document it has been neglected.

+GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
+
+   Routines to simulate the gigantic resonance of gammas in Tungsten
+   have been added.  The GPGIG routine is called in GUSTEP if a gamma
+   enter the calorimeter absorber.  This is the steering routine to
+   simulate the production of neutrons from gigantic resonance.  It
+   does checks on STEP lenght. If the range is smaller than the other
+   selected for that step, it does generate the neutron and stops the
+   gamma. Please note that the neutron has now a new particle
+   number. This is to tag the gigantic resonance neutrons.
