Examples
--------

The following should make big red arrows with green ellipses, outlined
in red. Note that the 39% confidence scaling will give an ellipse which
fits inside a rectangle of dimension Esig by Nsig::

    gmt psvelo << END -R-10/10/-10/10 -W0.25p,red -Ggreen -L -Se0.2i/0.39+f18p \
        -B1g1 -Jx0.4/0.4 -A1c+p3p+e -P -V > test.ps
    #Long. Lat. Evel Nvel Esig Nsig CorEN SITE
    #(deg) (deg) (mm/yr) (mm/yr)
    0. -8. 0.0 0.0 4.0 6.0 0.500 4x6
    -8. 5. 3.0 3.0 0.0 0.0 0.500 3x3
    0. 0. 4.0 6.0 4.0 6.0 0.500
    -5. -5. 6.0 4.0 6.0 4.0 0.500 6x4
    5. 0. -6.0 4.0 6.0 4.0 -0.500 -6x4
    0. -5. 6.0 -4.0 6.0 4.0 -0.500 6x-4
    END

This example should plot some residual rates of rotation in the Western
Transverse Ranges, California. The wedges will be dark gray, with light
gray wedges to represent the 2-sigma uncertainties::

    gmt psvelo << END -Sw0.4i/1.e7 -W0.75p -Gdarkgray -Elightgray -D2 -Jm2.2i \
        -R240./243./32.5/34.75 -Baf -BWeSn -P > test.ps
