Simulation values for comb resonances. Values for Bolo V and I have had a 1/sqrt(2) correction to complex components. Values for the voltage were calculated by differencing in the complex plane and then taking the magnitude i.e. sqrt( |Z1-Z2|^2 ).

Apparent V is the voltage calculate across the bias resistor, apparent I is the current through the SQUID coil from the network analysis and apparent P is the multiplication of the two previous.
