Beam positions through pair spectrometer magnet.

Redone study, June 7, 2011, full field maps.

Mapped Field, Results:

Note: The Z Pos is the position of the beam relative to the target. The X pos, is relative to the "absolute coordinates", which means relative to the beam when all magnets are off.

The center of the magnet in this simulation is at 88.485 mm. So to get the position of the beam relative to the center of the magnet, take (X_pos - 88.485 mm).

The last two columns are the numbers from Takashi's separate study, the results of which he email on June 6th 2011.
