Best fits of the attenuation curve derived with CIGALE with the ones from radiative transfer simulations of Seon & Draine (2016). The blue errors bars correspond to the attenuation curve and associated uncertainty derived with CIGALE estimated at wavelengths used in the radiative transfer simulations and covered by observations. The red line corresponds to the attenuation curve from radiative transfer simulations which best fits the CIGALE attenuation curve. The black lines represent the spectral coverage of the host galaxy observations.
