Fig3c_data.mat contains all the data to generate Fig.3c, showing the valley splitting as a function of total density

 Data_all_density [cm^-2] and Data_all_VS [eV] are all the extrapolated values for total density and valley splitting, respectively
 Data_all_density_fit [cm^-2] and Data_all_VS_fit [eV] is the linear fitting of all data, with fixed intercept to 0
 Data_all_slope_fit and Data_all_slope_fit_err are the slope and 2sigma error of the linear fitting
 Data_Paquelet_density [cm^-2] and Data_Paquelet_VS [eV] are the density  and valley splitting data from ref. Paquelet et al.
 theory_friesen_x [cm^-2] and theory_friesen_y [eV] generate the theoretical VS(n) dependance from ref. Friesen et al.
 sampleA_65mK_(...), sampleB_65mK_(...), sampleB_1700mK_(...), and sampleC_1700mK_(...) corresponds to the fitting parameters of each sample and temperature investigated
 (...)_A and (...)_A_err are the amplitude fitting parameter and relative 2sigma error from the fitting procedure
 (...)_deltan [cm^-2] is the valleys density difference fitting parameter
 (...)_n1, (...)_n1_err, (...)_n2, and (...)_n2_err [cm^-2] are the valley density 1 and 2 with relative 2sigma errors from the fitting procedure
 (...)_ntot [cm^-2] is the resultant total density from the fitting procedure
 (...)_tauQ and (...)_tauQ_err [s] are the single particle relaxation time and relative 2sigma error from the fitting procedure
 (...)_temp [K] is the temperature used for each device
 (...)_VS [eV] is the valley splitting extrapolated from the fitting procedure
