The Recycler is to be constructed utilizing combined function magnets. It is anticipated that production measurements of these magnets will
utilize a straight rotating coil aligned with the transverse center of the magnet. Since the reference orbit in these magnets follows an arc with
~11 mm sagitta the beam will experience magnetic fields that are different than those measured with the probe. The purpose of this note is to
provide a prescription for translating multipoles as measured by a straight probe into multipole content as seen on the reference orbit and to
evaluate the significance of these effects.
