MCMC Plots
- class radvel.plot.mcmc_plots.AutoPlot(auto, saveplot=None)[source]
Class to handle the creation of an autocorrelation time plot from output autocorrelation times.
- Parameters
auto (DataFrame) – Autocorrelation times output by radvel.mcmc
saveplot (str, optional) – Name of output file, will show as interactive matplotlib window if not defined.
- class radvel.plot.mcmc_plots.CornerPlot(post, chains, saveplot=None)[source]
Class to handle the creation of a corner plot from output MCMC chains and a posterior object.
- Parameters
post (radvel.Posterior) – radvel posterior object
chains (DataFrame) – MCMC chains output by radvel.mcmc
saveplot (str, optional) – Name of output file, will show as interactive matplotlib window if not defined.
- class radvel.plot.mcmc_plots.DerivedPlot(chains, P, saveplot=None)[source]
Class to handle the creation of a corner plot of derived parameters from output MCMC chains and a posterior object.
- Parameters
chains (DataFrame) – MCMC chains output by radvel.mcmc
P – object representation of config file
(Optional[string] (saveplot) – Name of output file, will show as interactive matplotlib window if not defined.
- class radvel.plot.mcmc_plots.TrendPlot(post, chains, nwalkers, nensembles, outfile=None)[source]
Class to handle the creation of a trend plot to show the evolution of the MCMC as a function of step number.
- Parameters
post (radvel.Posterior) – Radvel Posterior object
chains (DataFrame) – MCMC chains output by radvel.mcmc
nwalkers (int) – number of walkers used in this particular MCMC run
outfile (string [optional]) – name of output multi-page PDF file
