REFLUX - Modeling Multi-Wavelength Astrometry

REFLUX is a program that utilizes the Eclipsing Light Curve (ELC) code (Orosz, J.A., & Hauschildt, P.H. 2000, A&A, 364, 265) to model the flux-weighted astrometric reflex motion of a binary system with the specified parameters (Coughlin et al. 2010, ApJ, 717, 776; Coughlin, Harrison, and Gelino 2010, ApJ, 723, 1351; Coughlin and Lopez-Morales 2012, ApJ, 750, 100). REFLUX should only be used if you are interested in Astrometric motions specifically. If you just want to model a binary light curve, use ELC directly or another binary modeling program.

This page used to contain an html form front-end to the REFLUX code, but I have taken it down due to switching host institutions. If you want to use the REFLUX code, just e-mail me ( and I will send you the code directly with instructions on how to use it.
