Attached is the field for 40-00-16 turns of right septum, plotted on top of the left. It is plot with the tosca map which has 800A in the left and 895A in the right (these 2 current match well for 40-32-16 turns of right septum). One can see that after removing additional 4 wires from the 2nd coil in the top, the field in the right change shape a lot.

For the right septum, the field at the top is now ~10% lower than that at the bottom. That is, the field in the vertical edges(y=+/-9.5cm) are +/-5% away from that at the center(y=0).

For the left septum, the field at the top is now ~1.4% lower than that at the bottom. The field at the bottom (y=-9.5cm) is +3.5% larger than that at the center(y=0), while the field at the top is only 2% larger.

We have already seen acceptance lose in the right HRS due to t
