These are the constellation stick figures from Stellarium, so the GPL license applies (not public domain).
The code is an array of arrays. The first element of each array is the abreviation for the constellation name. Second is the number of lines in the stick figure. Lastly is a list of star IDs from the Hipparcos star catalog. Pull the RA/Dec coordinates from the catalog, convert the RA/Dec into which ever coordinate system is desired. The stars are to be taken in pairs, with the first being the start of the line, the next the end of the line, and the next star is the start of the next line.
