Dependence of the Mg II absorption profile on galaxy inclination and orientation. Left: $W_{\mathrm{r}}^{2796}$-b relation for the 66 isolated galaxies from our sample. The best log linear fits are shown for the whole sample, as well as for the low-α and high-α subsamples. The mid-α subsample is not sufficiently populated at small b. The shaded areas are 1-σ intervals. Right: The 0.1 Å Mg II covering fraction for the low-α and high-α subsamples, represented by the blue and red lines, respectively. The shaded areas are 1-σ intervals.
