The system is calibrated with reference to magnetic resonance observed between Zeeman states of the 6S$_{1/2}$ F = 4 $^{133}$Cs ground state. Magnetic field definition over the full 4{\\pi} solid angle is demonstrated, with one-sigma tolerances in magnitude, orientation and gradient of {\\delta}|B| = 0.94 nT, {\\delta}{\\theta} = 5.9 mrad and {\\delta}$\\nabla$ B = 13.0 pT/mm, respectively.
