I did not find the application of the constant kappa_zpsi in Table 3.2 in the paper. From the meaning of the characters, this variable should be applied to the formulas (3.61) and (3.62). But in fact these two formulas apply variable kappa_1,2. Please help me understand these two variables, thank you.
