Assessing differences between local dust attenuation and point source extinction within the same galactic environments

Fig. 6.

Values of R_{V_eff} as a function of the total optical depth normalization along the R axis τ_{V_R}, for a spiral (left) and elliptical galaxy (right). Different colors denote different observation angles, from 0° (face-on) to 90° (edge-on). An aperture radius of 20 kpc was used. The dashed black line reflects the true extinction R_{V_Zubko}.
