neat - 2.2-1 main

NEAT analyses lists of emission line fluxes measured from the spectra of
photoionised nebulae such as planetary nebulae and HII regions. It
determines the extinction, and then adopts a three zone model to determine
temperatures, densities, and ionic and total abundances, from collisionally
excited lines and recombination lines. It calculates uncertainties if
required, using a Monte Carlo technique.
