Figure 2

Parameter estimation. Illustration of peak parameter estimation. The figure displays a well-resolved peak in the region R={i:941.3Th x i 941.9Th}. In this example, the size of R equals 33, i.e. there are 33 pairs {(x i ,y i )}that enter a nonlinear least squares problem of the form (4). Under the assumption of an EMG model, the resulting fit is indicated by a solid line.
