Welcome to GalPaK’s documentation!¶
GalPaK 3D is a tool to extract Galaxy Parameters and Kinematics from 3-Dimensional data, using reverse deconvolution with the Bayesian analysis procedure Markov Chain Monte Carlo.

Do’s and Don’t¶
- The algorithm should never be used blindly and we stress that one should always
- look at the convergence of the parameters using
plot_mcmc()
,- investigate possible covariance in the parameters using
plot_correlations()
and/or fix a parameter with the option known_parameters to remove the degenerancy,- adjust the MCMC algorithm with the option random_scale (lower than 1 [default] for higher acceptance rate and vice versa) to ensure an acceptance rate of 30 to 50%.
