Best fits to the T-dependent LKS plots for all bands.

There is a slight mismatch between the points and the fit at higher temperatures due to noise in the FFT data, which can lead to the determination of slightly lower effective masses than those in reality, particularly in ε and θ (blue and green graphs). Note that the formula only weakly depends on the values for higher temperatures and the standard errors from the fitting procedure are on the order of 5%. From the quantization condition  ≥ k_BT, we expect oscillations from Weyl-pocket bands and consequently lower effective masses to sustain at higher T, as shown for the β band⁷.
