We have given detailed explanation of the STM spectra of impurity in superconducting BSCCO, including accurate verification of numerical data, by assuming that the spinless impurity is a Kondo hole at its two-channel fixed point. The impurity is assumed to be at its one-channel fixed point in order to explain its STM spectra. These assumptions are justified by extensive experimental evidence that the moderately doped cuprate crystal is a Kondo lattice.
