B.3 Constellation lines data file

This is a text file usually called lines.dat. It has no header. You can define paths of constellation lines by lists of stars that are ended with a semicolon `;'. You can insert superfluous whitespace as you wish, and comments after every `#'.

Stars are given in the usual way: Either by a pair of constellation abbreviation and Flamsteed number, as in

     ORI 19

(Rigel), or by `HD' and the Henry Draper catalogue number, as in

     HD 108248

PP3's constellation lines origin

I created the lines after my fancy. The Atlas für Himmelsbeobachter1 was an important source of inspiration though.
