(simply speaking: using two fitting constraints in one >FindFit) You have posted this question with the same wording at least once before that I know of. You are unlikely to get different answers to your question until you provide more details as to what you want to accomplish. If you missed responses to your previous post look at the archives for this group on Wolfram's web site and search for posts you have made to find the thread and answers.
