Hi everyone. I am currently trying to reduce the correlations between N and sigma squared. I have been told that multiple k-weight fitting is the way to go about this; but I am curious what the best method is to try and do this using Artemis. Is it simply a matter of clicking the other weighting options available? If so, what should I be looking for to determine whether my parameters are correct or not? I am not sure if this is a redundant question in terms of the mailing list; but I am a relatively new user and cannot remember seeing anything about it yet. Thanks. Dave Schmitter David C.
