ECE signals and plasma currents for different rotational transform profiles: (a) \(\iota /2\pi (0)=0.567\), (b) \(\iota /2\pi (0)=0.558\), and (c) \(\iota /2\pi (0)=0.549\). (d) Vacuum rotational transform profiles and (e) current at the start of the expansion of eITB as a function of \(\iota /2\pi (0)\) for the vacuum magnetic field.
