In GSIM

1. Calculate DOCA
2. DOCA    --->    TDRIFT   (linear function  ~  50 micron/ns)
3. TDC  =  TDRIFT  +  ( TOF  +  TPR ) (TOF: time of flight, TPR: propagation time)
4. TDC     stored in  DC0  bank
5. DOCA  stored in  (new) DOCA  bank

In GSIMKO

1. DOCA =  DOCA (DOCA bank) +  PAR* g(x)  (PAR: 200 micron, g(x): gaussian function)
2. DOCA --->  TDRIFT  (our choice of function, linear will be default)
3. (TOF  +  TPR) =  TDC (DC0 bank) - DOCA (DOCA bank) * C
4. TDC  =  TDRIFT  +  (TOF  +  TPR)

 

In RECSIS

1. TDRIFT   =   TDC  - (  TOF +  TPR )
2. TDRIFT   --->   DOCA   (our choice of function)
