addsmallcirc

Calculate and plot small circle on Stereo net
 at arbitrary azimuth, orientation and conical angle

aplot

Graphics for statistics on a sphere, as applied to geological fault data, crystallography, earthquake focal mechanisms, radiation patterns, ternary plots and geographical/geological maps.  Non-double couple plotting of focal spheres and source type maps are included for statistical analysis of moment tensors.
