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

Gliese 876 - Posterior Samples from RV Fit

This respository 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_4pl_fit.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 Masses (Earth masses)  
12-15 Eccentricities  
16-19 Arguments of periastron (degrees)  
20-23 Mean anomalies (degrees)  
24-27 Arg. of peri. plus mean anom. (degrees)  
28 Inclination (degrees)  
29-34 RV zero-point offsets (m/s)  
35-40 Sigma jitter terms (m/s)  
41 h (m/s)  
42 w  
45 logP_rot (log days) 
46 Lambda (days)  
47 log-likelihood
