Calculation of total magnitude of galaxies

Surface photographic photometry was not extended to low enough levels in order to warrant a suitable extrapolation leading to total magnitudes. We have computed, consequently, the luminosity up to the last measured isophote and we have obtained two parameters from the IS curve. Then, the values of N...
