Dear GATE users 
 
I'm designing a two-layer PET detector.
I know the time resolution for each crystal. 
The time resolution of the crystal at the bottom is 140.8 ps and the crystal at the top is 244.0 ps.  
How do I set the digitizer? 
Below is the digitizer in my macro file.
 
----------------------------------------------------------------------
# D I G I T I Z E R 
/gate/digitizer/Singles/insert adder
/gate/digitizer/Singles/insert readout
/gate/digitizer/Singles/readout/setDepth 4
 
/gate/digitizer/Singles/insert blurring
/gate/digitizer/Singles/blurring/setLaw linear
/gate/digitizer/Singles/blurring/linear/setResolution 0.15
/gate/digitizer/Singles/blurring/linear/setEnergyOfReference 511. keV
 
/gate/digitizer/Singles/insert thresholder
/gate/digitizer/Singles/thresholder/setThreshold 450. keV
/gate/digitizer/Singles/insert upholder
/gate/digitizer/Singles/upholder/setUphold 650. keV
 
/gate/digitizer/Singles/insert timeResolution
??????????????????????????????????????????? 
-----------------------------------------------------------------------
 
I need your help.
 
Thank you.
