These are the fits to the exitation curves measured during magnet
mapping:
The data points are fit to second degree polynomials
The field value correspond to the big component (vertical) and the units
are gauss.
The current units are amps.

D1:
       12600 - Field =  3.71 + 3.51*(3450-I) + 0.000046*(3450-I)^2

D2:
       Field =  -30.61 + 6.312*I - 0.00023*I^2
D3:
       Field = -2.11 + 4.226 * I - 0.000051 * I^2
D4:
       11896 - Field = -1.995 + 4.133 *( 2750-I) - 0.0000731 *(2750-
I)^2

D5:

       14509 - Field = -31.53 + 5.368*(2500-I) - 0.000185*(2500 - I)^2
