| Abstract: |
From photometric observations out to the tidal radii of the galaxies, we were able to identify hundreds of new carbon stars, to derive mean absolute magnitudes <Mi>, luminosity functions, and the spatial/radial distributions of the carbon stars in these galaxies. For each galaxy this new material will allow estimated of the tips of their RGBs to derive distance moduli, to derive C/M ratios of the AGB populations and bolometric magnitudes Mbol. At the end of our survey a comparison of all quantities of the late-type stars as a function of the properties of the host galaxies will be made possible. |
