Likelihood constraints

JESTER supports multiple observational constraints from multi-messenger astronomy to constrain the neutron star equation of state. These likelihoods can be combined in Bayesian inference.

Base class

Information about how the base likelihood class is implemented. Useful for those wishing to know how to extend jester and add new likelihoods.
