Direction Analysis
This graph shows the number of strikes detected per direction. It will give you a quick impression of where thunderstorms occur most often. Sharp spikes and dips may indicate sources of interference.

The red line indicates the average number of strikes per degree.

The graph is supplied as an SVG file. In Internet Explorer you must install the Adobe SVG Viewer plug-in to view it. Mozilla Firefox 1.5 (September 2005) will probably have native SVG support, it's already in the alpha version: Deer Park Alpha 2. Opera also has native SVG support.

An extra problem that may arise is caused by the fact that many Web Servers aren't configured to handle SVG files yet. They specify the wrong MIME type (txt) resulting in the source being shown instead of the graph.

The table above shows some characteristics of the antenna. It is based upon a small 5 degree window per direction. min is the minimum number of strikes in the 5 degree window, max is the maximum. avg is the total divided by 5. delta is the difference between min and max, divided by the average number of strikes per degree. (to quantify the N,E,W and S spikes) sensitivy is the actual count for a direction, divided by the expected count based upon the counts for the adjecant directions, eg: count(N) / (count(NE+NW)/2). This is to quantify the NE,SE,SW and NW drop in sensitivy.
