Supplementary Data for "New Constraints on Gliese 876 - Exemplar of Mean-Motion Resonance"

This repository contains supplementary material to the paperMillholland, S., Laughlin, G., Teske, J., et al. "New Constraints on Gliese 876 - Exemplar of Mean-Motion Resonance." 2018, AJ, 155, 106 The file, "posterior_samples.csv", contains DE-MCMC posterior parameter samples for the four-planet coplanar radial velocity fit, which is described in Section 4 and summarized in Table 4 of the paper. The epoch of fit is 2450602.09311 BJD. To fit within file size limitations, the posterior samples were thinned by uniqueness. The columns of the files are provided below. For the planet parameters, the columns are in orbital period order (i.e. planets "d", "c", "b", "e"). The stellar mass is 0.37 M_Sun. 0-3 Periods (days) 4-7 Semi-major axes (AU) 8-11 RV semi-amplitudes (m/s) 12-15 Masses (Earth masses) 16-19 Eccentricities 20-23 Arguments of periastron (degrees) 24-27 Mean anomalies (degrees) 28-31 Arg. of peri. plus mean anom.
