The top panel shows the likelihood distribution of the parameters (﹩{ln}({\nu }_{0})﹩; (kpc⁻³), h _z ( kpc), and Z ₀ ( kpc)) for 8–9 kpc, drawn from the MCMC simulation. The uncertainties in the estimates are determined using the 15th and 85th percentiles of the MCMC samples. The bottom panel shows the fitting results and relative errors of the model and data. It appears that there are some oscillations in the solar neighborhood.
