Bayes-ME is a computer program to carry out Bayesian inference of thermodynamical and magnetic properties of solar/stellar magnetic elements applying the Milne-Eddington model atmosphere to observed Stokes profiles. The result are probability distribution functions for each model parameter with complete statistical significance.
Bayes-ME can be downloaded here. Follow the steps in the manual after decompressing the file to compile the code. You will need a Fortran 90 compiler.
An example of an application can be found in Asensio Ramos (2009), where quiet Sun data observed with Hinode is analyzed with Bayes-ME, producing posterior probability distribution functions for all the model parameters. An example of the output of the code is presented below for some pixels of the field-of-view.
