| CALL GSDIGI (ISET,IDET,LTRA,NTRA,NUMBV,KDIGI,IDIG*) |
+------------------------------------------------------------------------+

Stores element values for current digitisation into the data structure JDIGI.

ISET
set number
IDET
detector number
LTRA
list of NTRA track numbers producing this digitisation
NUMBV
volume numbers corresponding to list NAMESV of GSDET
KDIGI
integer array of values for current digisation elements
IDIG
on return, current digitisation number. If =0 digitisation has not been stored. 

             +----------------------------------------------+
             | CALL GPDIGI (IUSET,IUDET) |
             +----------------------------------------------+
Prints JDIGI banks for detector IUDET of set IUSET.

IUSET
user set identifier if IUSET=0 prints all JDIGI banks of all sets
IUDET
user detector identifier if IUDET=0 prints digitisations in all detectors of set IUSET 

+-------------------------------------------------------------------------------------------------------------+
|CALL GFDIGI (IUSET,IUDET,NTDIM,NVDIM,NDDIM,NDMAX,NUMVS, LTRA*,NTRA*,NUMBV*,KDIGI*,NDIGI*) |
+-------------------------------------------------------------------------------------------------------------+

Returns the digitisations for the physical volume specified by the list NUMVS with generic volume name IUDET belonging to set IUSET.

IUSET
user set identifier
IUDET
user detector identifier (name of the corresponding sensitive volume)
NTDIM
1st dimension of LTRA (max. number of tracks contributing)
NVDIM
1st dimension of NUMVS, NUMBV (argument NV of GSDET)
NDDIM
1st dimension of KDIGI (argument ND of GSDETD)
NDMAX
is the maximum number of digitisations to be returned
NUMVS
is a 1-Dim array that must contain on input the geometric path of the detector volume to be selected. All 0 interpreted as 'all physical volumes with generic name IUDET
LTRA
is a 2-Dim array that will contain on output for each digitisation the numbers of the tracks which have produced it
NTRA
is a 1-Dim array that will contain on output for each digitisation the total number of tracks contributing. In case this number is greater than NTDIM, only the first NTDIM corresponding tracks can be returned on LTRA
NUMBV
is a 2-Dim array that will contain on output for each digitisation the list of volume numbers which identify each physical volume
KDIGI
is a 2-Dim array that will contain the NDIGI digitisations
NDIGI
is the total number of digitisations in this detector. In case the total number of digitisations is greater than NDMAX, NDIGI is set to NDMAX+1 and only NDMAX digitisations are returned

  1. KDIGI(1,I) = digitisation type 1 for digitisation number I
  2. NUMBV(1,I) = volume number 1 for digitisation number I
  3. LTRA (1,I) = first track number contributing to digitisation number I

In the calling routine, the arrays LTRA, NTRA, NUMVS, NUMBV, KDIGI must be dimensioned to: 

   LTRA (NTDIM,NDMAX)
   NTRA (NDMAX)
   NUMVS(NVDIM)
   NUMBV(NVDIM,NDMAX)
   KDIGI(NDDIM,NDMAX)
