Dispersive shift as a function of VG and B|| a At B|| = 0 T, |S21| (Norm.) versus f and VG (with VCNP = 300 mV subtracted) shows the symmetric band dispersion of graphene with additional fluctuations we attribute to UCF. b ft (red circles) extracted from χ (black diamonds) versus B|| at VG = 0 V, showing ft is not significantly affected. c Repeating a at B|| = 1 T with VCNP = 430 mV subtracted confirms the graphene JJ behaves equivalently to B|| = 0 T. The variation observable in b and shift in VCNP between a and c we attribute to slow gate drift
