Abstract (from CDS):

We present an analysis of Hubble Space Telescope/WFPC2 images of nine nearby galaxies in Sculptor. We derive their distances from the luminosity of the tip of the red giant branch stars with a typical accuracy of ∼12%. Their distances are 4.21-Mpc (Sc 22), 4.92-Mpc (DDO 226), 3.94-Mpc (NGC 253), 3.40-Mpc (KDG 2), 3.34-Mpc (DDO 6), 3.42-Mpc (ESO 540-030), 4.43-Mpc (ESO 245-05), 4.27-Mpc (UGCA 442), and 3.91-Mpc (NGC 7793). The galaxies are concentrated in several spatially separated loose groups around NGC 300, NGC 253, and NGC 7793. The Sculptor galaxy complex together with the CVn I cloud and the Local Group form a 10-Mpc filament, apparently driven by the free Hubble flow.
