alfa - 2.2-1+b3 main

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.
