Hi,
thanks for your nice work and detailed documentation. This programm helps me greatly with my research.
When I was reading the source code on calculating the pair interaction, I think the programm may have missed a minus sign. According to the theory, the interaction term should read

(I directly snipped it from your paper.) There is a (-1)^{L_2} sign term in it. However, I did not find such term in your programm. (Also, the \sqrt{(2L_1+1)(2L_2+1)} seems to be missing as well, however, this term is by chance cancled out in calculating the dipole-dipole interaction .) I could be wrong, but still decided to raise this issue. What do you think?
