StarPlot 0.95.5 (Default branch)
05-16-2008
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.

starconvert(1) General Commands Manual starconvert(1) NAME
starconvert - convert text data files to StarPlot format SYNOPSIS
starconvert [ options ] spec-file input-file [ output-file ] DESCRIPTION
Although many stellar data files are publicly available on the Internet from NASA and other astronomical organizations, there is no set format for these files. The program starconvert acts as a buffer between this confusion and the format in which StarPlot requires data files. To do so, it uses a specification file that details how various fields of stellar data (name, distance, right ascension, etc.) may be extracted from the original data file. On the StarPlot web site are available some packages of data that include both an original data file from NASA, and also a specification file. These packages are referred to as "data sets", from which starconvert can produce a data file in StarPlot format. For ease of use, this should be done via the starpkg(1) shell script. The starconvert command uses the specifications in spec-file to convert input-file to StarPlot data format and writes the results to out- put-file if specified, or standard output if not. The first two arguments are required. Exactly ONE may be replaced with a dash `-' for reading from standard input. OPTIONS
-- Signals the end of the options. This allows you to use a spec-file whose filename begins with the '-' character. --add-sun Add an entry for the Sun to the generated StarPlot-format data file, if it is not already present in the original raw data file. This is the default behavior, so this flag has an effect only if it reverses an earlier --no-add-sun flag. --no-add-sun Do not add an entry for the Sun to the generated StarPlot-format data file, unless it is present in the original raw data file. Adding the Sun is otherwise done by default, since most star catalogs do not include it. SPECIFICATION FILES
For detailed information on how to write a specification file, see the example file listed below. Be aware that I expect to change the default format of starconvert spec files after version 1.0, although starconvert will remain backwards-compatible. FILES
