Hypersurface Fit (IMAGE) DOE/Argonne National Laboratory Caption This is an example of a 'hypersurface' fit to many experiments with slightly different noise parameters, 1 and 2. Black points are measurements of an observable with different noise rates. The red 'X' is the noise-free result. Blue, orange and green surfaces are first, third and fourth order fits.
