[ADVANCED\]MOMENTS [Image|File.Ext] /METHOD Mean|Peak|Parabola [/MASK] [/RANGE Min Max TYPE] [/THRESHOLD Thre [Unit]]

Specify which method to be used to compute the velocity and peak values. The default method, MEAN, computes an intensity weighted velocity, and takes the peak intensity at each pixel. Method PEAK takes the velocity at the peak intensity. Method PARABOLA makes a parabolic fit over 3 channels around the peak intensity channel to derive the velocity, and takes the peak value of this parabola for the peak brightness.
