This repository contains supplementary material to the paper Millholland, S., Laughlin, G., Teske, J., et al. "New Constraints on Gliese 876 - Exemplar of Mean-Motion Resonance." 2018, AJ, in press 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").  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. (degrees)   32-35 e cos(arg. peri.) 36-39 e sin(arg. peri.) 40-43 Longitude of the ascending node (degrees)  44-47 Inclination (degrees)   48-53 RV zero-point offsets (m/s)   54-59 Sigma jitter terms (m/s)  60 h (m/s)   61 w   62 logP_rot (log days)  63 Lambda (days)   64 log-likelihood   Feel free to direct questions or comments to sarah [dot] millholland [at] yale [dot] edu.
