Whether the definition of the g_dgdr_gauserf function needs to be adjusted？

[ExuberantWitness]

While comparing the code to the corresponding paper, I seem to have noticed that "g_dgdr_gauserf" has one Sigma less than the corresponding formula. I wonder if this will affect the final result

Better late than never! =]

The second output of g_dgdr_gauserf(...) later on gets divided by sigma*r to end up obtaining the equation that you show. The mismatch between the implementation and the dissertation might be a little confusing, but that way we were able to generalize the kernel (we can switch to any kernel while keeping the same UJ function)
