The authors agree to the point made by Nadarajah, et. al. that the model that employs the mixture of Gaussian distributions is not a new idea. However, the mixtures of Gaussian distribution was only used to clarify the relationship between the local critical current density (Jc) distribution and the microstructure of the samples to successfully explain the relationship between the local Jc distribution and the microstructure of the Bi2212 materials. Because the local Jc distributions are directly connected to the electric fields versus current density (E-J) characteristics, the model permits the interpretation of the complicated E-J properties by means of the microstructures.
