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
  1. look at the chain using plot_mcmc(),
  2. look at the convergence of the parameters using plot_geweke(),
  3. investigate possible covariance in the parameters using plot_correlations() and/or fix a parameter with the option known_parameters to remove the degenerancy,

(4) 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%. or use the autorun().
