Figure 2

Screen shot of a graphical Gaussian curve fitting example in SDAR. Shown is the fitting of elution peaks obtained in a size exclusion chromatogram with four Gaussian functions. The user can place a Gaussian function with a mouse right-click at a particular x-position in the graph. Using the peak and half-width anchor points which can be dragged by a mouse left-click, the Gaussians can be adjusted to fit the experimental peaks. The parameter values as well as the goodness of fit of the resulting sum curve (black) are updated in real time in the inset window.
