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.
