HI, I think the large alpha_x ineffiency is more due to the fact that the matching tof-track is worse since it involves slats from outer panels more (I'm not talking about the panels Peter has removed on purpose). The matching in the x direction of each panel is better for middle panels. In the y direction, this behaviour is even worse. Since the y matching relies on the slat speed of light calibration, it is much better in the middle panels where most of the tracks point to.
