I revisit the Cepheid-distance determination to the nearby spiral galaxy M101 (Pinwheel Galaxy), in light of several recent investigations questioning the shape of the interstellar extinction curve. I find that the (steeper) extinction curve of Fitzpatrick Massa (2007) is slightly favoured relative to the vastly more cited curve of Cardelli et al. (1989), and this consequently increases the inferred distance modulus by ~0.06 mag. ...

... Fig. 1a,b. Location of slit spectrograms on the HА-line image of IC10. ... Relative abun dances Relative abundances of oxygen are derived using three methods. ... Figures 2, 3, 4 show the distributions of the inferred 12+log(O/H), log(N/O), log(S/O) values along the slits; we averaged the abundances over HII re gions from the catalog of Hodge and Lee [5]. ... Relative oxygen abundance along the slits. ... Relative nitrogen abundance along the slits. ... Relative sulf ur abundance along the slits. ...
