Fig2b_data.mat contains all the data to generate Fig.2b, oscillatory longitudinal magnetoresistance as a function of inverse perpendicular magnetic field at 1.7 K

 traces labelled from 1 to 6 corresponding to low to high accumulation gate, respectively
 invB [T^-1] is the inverse perpendicular magnetic field
 delta_rhoxx [Ohm/sq.] is the oscillatory component of longitudinal magnetoresistance
