Although the authors disfavored the explanation of the conductance resonances based on resonant tunneling (RT) through an impurity state, I believe that it should not be dismissed and can explain a number of experimental observations very well. In particular, I point out a new characteristic signature of RT in the quantized Hall regime: the quantization of the slopes of the resonance tracks on the magnetic field-gate voltage plot.1 page, revtex, submitted to Phys.
