[gate-users] Meaning of XYZ Coordinates in ASCII File

[Ray Raylman]

Hi All-

I am using the ASCII output of the coincidence file from GATE, and I
would like to know what event the x, y and z coordinates are specifying.
 Are these the coordinates of the first interaction in the detector, the
first Photoelectric event, the position of the endpoint of the photon or
something else?

Thanks, Ray
