naima

naima is a Python package for computation of non-thermal radiation from relativistic particle populations. It includes tools to perform MCMC fitting of radiative models to X-ray, GeV, and TeV spectra using emcee, an affine-invariant ensemble sampler for Markov Chain Monte Carlo.

naima is named after a ballad composed by John Coltrane in 1959 which appeared in the albums Giant Steps (1959) and Live at the Village Vanguard (1961).
