[/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.
