Surface brightness profiles of NGC 3486 in the g band (upper panel) and r band (central panel) using LIGHTS data. The surface brightness profiles shown correspond to the background-subtracted data (green), the Wiener-Hunt deconvolved data (blue), and the data for which the PSF effect has been removed (orange). These profiles were obtained using a fixed ellipticity and PA representative of the outer parts of the galaxy (see the main text for details). Only values above 3σ the noise of the data are shown. The pink lines correspond to the IMFIT models we used to model the Wiener-Hunt deconvolved light distribution of the galaxy. The vertical dashed black lines highlight the location of R_edge with the corresponding shaded gray uncertainty, dashed vertical purple lines highlight the location of R_PSFeff (the radius where the PSF starts to be noticeable), and horizontal blue lines represent the data surface brightness limiting depth. The g − r average radial profiles prior and after deconvolution are shown in the bottom panel.
