How to adjust the parameter coprune_threshold on other datasets

[tb2-sy]

Hi, thanks for your nice work! I am applying your method to other datasets. The Gaussian point is randomly initialized between -1.3 and 1.3. How can I adjust the coprune_threshold? I have now set it to 0.05, but there has been no decrease in fitness and inlier_rmse. Looking forward to your reply.
