Routines to store and retrieve DIGItisations
CALL GSDIGI
(ISET,IDET,LTRA,NTRA,NUMBV,KDIGI,IDIG*)
ISET
IDET
LTRA
NUMBV
KDIGI
IDIG
(INTEGER) set number;
(INTEGER) detector number;
(INTEGER) array of NTRA track numbers producing this digitisation;
(INTEGER) volume numbers corresponding to list NAMESV of GSDET;
(INTEGER) array of current digisation elements;
(INTEGER) stored digitisation number, if 0, digitisation has not been stored.
Stores element values for current digitisation into the data structure JDIGI.
CALL GPDIGI
(CHSET,CHDET)
CHSET
CHDET
(CHARACTER*4) set name, if ’*’ prints all JDIGI banks of all sets;
(CHARACTER*4) detector name, if ’*’ prints digitisations in all detectors of set; CHSET
Prints JDIGI banks for detector CHDET of set CHSET.
CALL GFDIGI
(CHSET,CHDET,NTDIM,NVDIM,NDDIM,NDMAX,NUMVS,
LTRA*,NTRA*,NUMBV*,KDIGI*,NDIGI*)
CHSET
CHDET
NTDIM
NVDIM

NDMAX
NUMVS
LTRA
NTRA
NUMBV
(INTEGER) set name;
(INTEGER) detector name;
(INTEGER) 1 s t dimension of LTRA, maxmum number of tracks contributing to each hit to be
returned;
(INTEGER)1 st dimension of arrays NUMVS, NUMBV, same as argument NV of GSDET;
(INTEGER)1 st dimension of KDIGI, same as argument ND of GSDETD;
(INTEGER) maximum number of digitisations to be returned, second dimension of arrays NTDIM,
NUMBV and KDIGI;
(INTEGER) is a 1-dim array of length NVDIM that contains the copy numbers identifying the
detector to be selected, all 0 is interpreted as all copies of detector CHDET;
(INTEGER) is a 2-dim array NTDIM,NDMAX that contains for each digitisation the numbers of
the tracks which have produced it;
(INTEGER) is a 1-dim array of length NDMAX that contains, for each digitisation, the number of
tracks contributing, in case this number is greater than NTDIM, only the first NTDIM corresponding
tracks are returned on LTRA;
(INTEGER) is a 2-dim array NVDIM,NDMAX that contains, for each digitisation, the list of volume
numbers which identify each detector;
