Vertical Magnetic Field in Storage Ring at Magic Momentum

This data from POISSON calculated field by Danby & Jackson.
Transformed this to get By, dBy/dx, dBx/dY in injection coord
frame (s axis downstream, tangent to ring but displaced 
outward 76 mm, x axis outward along radius through nominal end 
of inflector.) By used to trace beam axis, gradients used for 
hor & vert focusing effects in the main fringe field.

     7.1120       /Radius of storage orbit in meters

Column 1: Radial distance outward from storage orbit in mm.
Column 2: By in Tesla
Column 3: Gradient dBy/dR in Tesla/m
