I use MINUIT to do some Chi2 and maximum likelihood fits. I need to fit variable1 first, then variable2, then variable2 vs variable1 in one program run. When fitting variable1 and variable2 independently, MINUIT replaces the starting values by that that are found, then uses these values as starting values for the next 2D fit - how do I prevent it, ie how do I instruct MINUIT to reset itself (not completely, it would be handy to keep parameter definitions, step sizes and the like) and use the initial values?
I tried the END command but MINUIT seems to ignore it (no messages, no effects).
Thanks.
