Command Line Option parsing
;login:: the magazine of USENIX & SAGE, 2014Co-Authors: David M BeazleyAbstract:If I look back, an overwhelming number of the Python programs I have written have been simple scripts and tools meant to be executed from the Command Line. Sure, I’ve created the occasional Web application, but the Command Line has always been where the real action is. However, I also have a confession—despite my reliance on the Command Line, I just can’t bring myself to use any of Python’s built-in libraries for processing Command Line Options. Should I use the getopt module? Nope. Not for me. What about optparse or argparse? Bah! Get out!

EXOFASTv2: A public, generalized, publication-quality exoplanet modeling code
2019Co-Authors: Eastman, Jason D., Rodriguez, Joseph E., Agol Eric, Stassun, Keivan G., Beatty, Thomas G., Vanderburg Andrew, Gaudi B. Scott, Collins, Karen A., Luger RodrigoAbstract:We present the next generation public exoplanet fitting software, EXOFASTv2. It is capable of fitting an arbitrary number of planets, radial velocity data sets, astrometric data sets, and/or transits observed with any combination of wavelengths. We model the star simultaneously in the fit and provide several state-of-the-art ways to constrain its properties, including taking advantage of the now-ubiquitous all-sky catalog photometry and Gaia parallaxes. EXOFASTv2 can model the star by itself, too. Multi-planet systems are modeled self-consistently with the same underlying stellar mass that defines their semi-major axes through Kepler's law and the planetary period. Transit timing, duration, and depth variations can be modeled with a simple Command Line Option. We explain our methodology and rationale as well as provide an improved version of the core transit model that is both 25\% faster and more accurate. We highlight several potential pitfalls in exoplanet modeling, including the handling of eccentricity in transit-only fits, that the standard exoplanet convention for $\omega$ uses a left-handed coordinate system, contrary to most modern textbooks, how to avoid an important degeneracy when allowing negative companion masses, and a widely unappreciated, potential 10-minute ambiguity in the reported transit times. EXOFASTv2 is available at https://github.com/jdeast/EXOFASTv2 . The code is written in IDL, and includes an executable that can be run freely and legally without an IDL license or any knowledge of the language. Extensive documentation and tutorials are included in the distribution for a variety of example fits. Advanced amateurs and undergrads have successfully performed sophisticated global fits of complex planetary systems with EXOFASTv2. It is therefore a powerful tool for education and outreach as well as the broader professional community.Comment: 51 pages, 14 figures, 3 Tables. Submitted to PASP. Comments welcom
