Photons from GAMPECK: Output bank PGAC

This bank is written on POTs , DSTs and MINIs since December 1994 by JULIA version 272 and after, or MINI version 10 and after.

On these datasets, the photons from the old GAMPEC package (bank EGPC, see above) or GAMPEX (bank PGPC, see above), are no more available.

XPGAC (I)

.TRUE. if GAMPECK data are available for ``track'' I of the GAT section

QPGPR1 (I)

Energy fraction in stack 1

QPGPR2 (I)

Energy fraction in stack 2

QPGPF4 (I)
