Update the chisq expression in order to take the condition where the uncert is 2-D i.e. a covariance matrix. In this case, chisq = (data-model).T @ inv(sigma) @ (data-model).

Hi @alulujasmine |

Thanks for your reply! I am very sorry that I didn't test it because I don't know how to do it. I had tried to download the whole updated package and run it. It didn't work. Thank you very much for taking this update into consideration and being willing to test it! |
