JDIG
= LQ(JDIGI-ISET), pointer to digitisations for set ISET
JDD
= LQ(JDIG-IDET), pointer to digitisations of detector IDET of set ISET
IQ(JDIG+IDET)
pointer to last word of last digitisation for this detector
IQ(JDD+1)
1st word of first digitisation
IQ(JDD+N+1)
1st word of second digitisation JS=LQ(JSET-ISET) JD=LQ(JS-IDET) NWD=IQ(JD+5) NTRA number of tracks contributing to first digitisation N=NWD+NTRA/2+1 (N varies from digitisation to digitisation)
The JDIGI structure is filled with the routine GSDIGI. The routine GFDIGI can be used to get the digitisations for a detector IDET in set ISET.
