The shaded region is where microwave spectra show a resonance of amplitude σpk>2 μS. The edges of the measurement range resulting from limits in the sample density range obtainable from gating are shown as dotted lines. The measurement range limit due to the maximum magnetic field is the upward sloping dashed-dotted line. The squares and circles denote the transition filling factors, ν1 and ν2, respectively, as identified from minima in the resonance peak conductivity, σpk, versus ν with error due to the width of the minimum.
