    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.
