Automated Line Fitting Algorithm


ALFA measures fluxes in emission line spectra, such as those of planetary nebulae and HII regions, using a genetic algorithm to rapidly optimise fits to large numbers of lines simultaneously. It can subtract night sky emission lines before fitting the nebular lines if necessary. It can read plain text files containing 1D spectral data, or FITS files containing 1D, 2D or 3D datasets.
