Analysis of spin flip data in rings with nearly full Siberian Snakes

I calculate theoretical values to fit experimental measurements of spin flip resonance widths in rings with nearly full strength Siberian Snakes. Some measurements were made using an rf solenoid, and others using vertical field rf dipoles. In particular, the staff of the MIT-Bates Linear Accelerator Laboratory kindly made available to me additional unpublished data for the spin flipping of stored polarized electrons at 850 MeV using a vertical field rf dipole spin flipper.
