The magnetic-field pitch-angle profile, gamma(p)(R) = tan(-1)(B-pol/B-
tor), is measured on TFTR using a motional Stark effect (MSE) polarime
ter. Measured pitch angle profiles, along with kinetic profiles and ex
ternal magnetic measurements, are used to compute a self-consistent eq
uilibrium using the free-boundary variational moments equilibrium code
VMEC. Uncertainties in the q profile due to uncertainties in gamma(p)
(R), magnetic measurements and kinetic measurements are Found to be sm
all. Subsequent uncertainties in the VMEC-calculated current density a
nd shear profiles are also small.
