If you’ve been working on the first systemic challenge system, please submit your fit as an ascii file to the e-mail address listed on the web-page given in the Sky and Telescope article. At 00:00 UT Sept. 14th (JD 2453992.5) I’ll close the submissions and see who wins the Star Atlas.
Don’t hesitate to submit if your chi-square is still far from 1.00. Our first challenge system turned out to be a bit harder than we anticipated. Next week’s system will be equally interesting from a dynamical point of view, but will be a lot easier on the ol’ CPU.
