This is a dedicated routine to produce bipolar outflow maps, with op-
timum signal to noise ratio and little bias. It takes as input a cube
(N by NX by NY) with the velocity along the first axis, and produces a
pseudo-cube cube (3 by NX by NY) containing the maps of the line width
and of the red and blue lobes integrated intensities.
For each spectrum, the algorithm determines the peak channel, then de-
termines on each side of this channel the velocity at a given
threshold, given as ratio to peak value. From this velocity, it
integrates out to a second threshold. The area found is the
contribution to the blue (or red) lobe of the flow.
