The digitised hits format should in principle simulate the detector readout format which may be different for different detectors. These formats are not yet defined. But for practical reasons below is presented a digitisation bank format for pixel detector:
...
#. Pixel detector DIGItisation definition
#. set detector element
:DETD :PBXL :PXBD
4 #. no. of digitisation elements
1 :V 7 #. row number
2 :W 9 #. column number
3 :TIME 4 #. time
4 :ADC 12 #. charge
...
The DIGI bank will be filled by the GEANT DIGI package
GSDIGI (ISET, IDET, LTRA, NTRA, NUMBV, KDIGI, IDIG)
which sets up the references to the KINE structure (via list of tracks
LTRA(1:NTRA) which causes this digitisation) so that for each digitisation
one can find the track(s) responsible for one digitisation.
