Magnetic Field From Feshbach Coils

See Dylan #2 pg. 84 for details of measurement.
See Feshbach Coil calculator for details of calculation.

*Probe was coarsely positioned at the center by finding the minimum field of the coils in anti-helmholtz configuration.
*The gradient at 4mm from the field center corresponds to the displacement of atoms in the lattice from the field center.
