% Map of the number density of genesis points, defined as the first point
% of each track where wind speeds exceed _startv_ , filtered (if desired) to
% include only those events whose winds speeds exceed some threshold, _peakv_
% as set in the _params.m_ file. The track density is in number per year per
% 1-degree latitude square. The resolution at which the density is
% calculated and other features of the map can be specified in the _params.m_
% file.

% This version of the script uses the free m_map routines, which are
% included with the script set. Various map properties can be set in
% _params.m_ .
