What is it about?
Self heating effect and noise rounding effect cannot be avoided completely. Even in this situation, you can determine Ic and Rn of RSJ-model-compatible junctions by following this standard measurement method. In addition, standard graphical symbols for superconductor electronics have been defined: Josephson junction, normal-superconducting boundary, superconducting connection, and normal connection.

Why is it important?
Ic and Rn are the crucial parameters to design superconductor circuit; therefore, this standard method is expected to play an important role in quantum technology.
