HITS399 The JDIGI data structure

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.
