I'm working on a project which uses BlackMax, and I have a few questions if you could please answer: 1- The generated cross-section is very small (10^-10 pb roughly). How can I increase it? 2- In calculating the horizon radius of the BH, a parameter "a" is used that is related to the angular momentum. How can I find this "a" in the code? I appreciate your kind help and reply Best Regards Ali
