Graphics for Spherical Distributions and Earthquake Focal Mechanisms

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.



3.2 2012-12-17 Major change: added non-double couple decomposition to focal mechanisms. Added Tape and Hudson displays for source types. Added NCP and NIP options in PlotPTsmooth for controlling the size of images. Removed vignette focalmec.
