Radiant

Download Radiant (author Rainer Arlt)

The software calculates density distributions of meteor radiants. The disk-read procedures interpret meteor co-ordinate data in the PosDat and FIDAC formats. The user should have some basic knowledge of creating dBase files. The density distributions are gnomonically projected, thus simplifying the calculating procedures. For most radiant searches the investigated area is small enough (<20°rees;across) that the scale change over this gnomonic chart can be neglected.

Radiant knows three methods of radiant determinations: backward tracings, intersection counts and probability distributions.

Radiant is a product which developed by its users. I would like to specially thank Malcolm J. Currie for his numerous suggestions, Andre Knofel for testing the current version and setting up the FIDAC file structure, Ralf Koschack for mathematical ideas and the analysis of plotting and velocity errors, Luis R. Bellot for modifying the angular speed formula, Detlef Koschny for setting up the PosDat file structure and many more.
