(a) Resonance frequency normalized to its value at the lowest measured temperature, \(T_0\), as a function of temperature. Data were interpolated by means of the equations described in the text. (b) Penetration depth and (c) surface resistance, as deduced from the fitting procedure for the CPWRs #1 and #2, from measurements in zero DC field.
