Difference is such a quantity: When we make a projection of a track to the x-z or y-z plane, (given that the z coordinates have been fixed when we were building the GEM detectors, our software only looks for the x and y postion), we will get three points on the x-z (y-z) plane, then we make a line through two points among the three points and predict the third point's position according to the line, we record the value difference between the pridiction and the projection values, that is a difference. | ||
