Methods Documentation

fit(gal, output_options)[source]

Fit observed kinematics using MCMC and a DYSMALPY model set.

Parameters:

gal (Galaxy instance) – observed galaxy, including kinematics. also contains instrument the galaxy was observed with (gal.instrument) and the DYSMALPY model set, with the parameters to be fit (gal.model)
output_options (config.OutputOptions instance) – instance holding ouptut options for MCMC fitting.

Returns:

mcmcResults – MCMCResults class instance containing the bestfit parameters, sampler_results information, etc.

Return type:

MCMCResults instance
