StarPlot is a GTK-based program, written in C++,which can be used interactively to viewthree-dimensional perspective charts of stars.Charts can be recentered, rotated, or zoomed in orout with a mouse click (this can also, of course,be done via dialog boxes for more precision).Stars may be viewed (or ignored) by spectral classand absolute magnitude. Other features includesupport for both celestial and galactic coordinatesystems, the ability to display extendednon-stellar objects, and a pop-upHertzsprung-Russell diagram. StarPlot is alsopackaged with starconvert, a utility whichconverts line-oriented stellar data records toStarPlot format. Most star data files available onthe Internet can be converted this way if a shortfile describing the original file format isprovided to starconvert. License: GNU General Public License (GPL)Changes:
StarPlot now permits the use of parsecs instead oflight-years as the primary distance unit, and alsocan show distances in astronomical units and milesor kilometers at close range. A new button permitsthe chart to be set to the orientation of a volumeof space as seen from Earth. A new dialog boxmakes it easy to calculate the distance betweentwo arbitrary points in space. More documentationhas been written. Some bugs preventing compilationwith modern g++ versions have also been fixed.
