What is the actural role of $C_{\sigma}$?

Hi, I'm recently read your paper. But i'm confuse about $C_{\sigma}$​​​​​​​​ in formula 11, which will be eliminated by ${\sigma \sqrt{2\pi}}$​​​​​. Besides, did C here is the implementation of $C_{\sigma}$​​​​​​​​? It did not use in return.

Hi, the function is used in the paper is loss_structrue, and its corresponding subfunction is CalPairwise.

CalPairwise_t was actually used in the rebuttal phrase. I tried to change the Gaussian distribution to student-t distribution.
