    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.
