If the scale on these plots is really in mm, then the tail reaches out to almost 5 mm. If the harp should travel horizontally, that can't fit through the target window with the raster on. The target window is 0.75 inch = 19 mm wide and 0.5 inch = 13 mm deep. At 30 degree, the horizontal clearance is roughly 19 mm x cos(30) - 13mm *sin(30) = 10 mm. The raster itself has been 4 to 5 mm in this direction. If the beam is roughly centered, that leaves only 2.5 to 3 mm on each side.
