Look-alike galaxies: - HI observations for look-alike galaxies of four calibrators

We present a programme aiming at applying the Tully-Fisher relation for galaxies with the same morphological type and the same inclination (look-alike galaxies or sosie galaxies) as calibrating galaxies. The advantage of sosie galaxies is discussed. In particular, it is shown that using sosies of bright calibrators will allow us to explore the universe deeper and more efficiently...
