Kalyan posted the beam positions that are centered at the target in halog 364625 (at these positions, the aluminum hole appears to be at the center of the slow raster pattern). They should be (all in mm):
BPMAX: -0.3 (H05AX) BPMAY: -1.4 (H05AY) BPMBX: -1.1 (H05BX) BPMBY: -2.7 (H05BY)
These numbers are written on the whiteboard now.
