Figure: Layout of the JDIGI data structure

JDIG=LQ(JDIGI-ISET) pointer to digitisations structure for set number ISET
JDD=LQ(JDIG-IDET) pointer to digitisations of detector numberIDETof set number ISET
IQ(JDIG+IDET) pointer to last word of last digitisation for detectornumber IDET
IQ(JDD+1) 1st word of 1st digitisation
IQ(JDD+N+1) 1st word of 2nd digitisation
JS=LQ(JSET-ISET) pointer to the structure containing the descriptionof digitisations of set number ISET
JD=LQ(JS-IDET) pointer to the structure containing the descriptionof digitisations of detector number IDET
NWD=IQ(JD+5) number of elements of digitisation of set/detectorISET/IDET
NTRA number of tracks contributing to 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.
