Comparison between estimated dust attenuation and expectations based on spectro-photometric diagnostics. Left-hand figure: Distribution in rest-frame U-V, V-J colour for our sample galaxies. Filled (empty) symbols refer to the golden (silver) sample, while circles and stars distinguish Q and SF galaxies. The colour-coding indicates the dust attenuation A_g estimated from BaStA fitting of spectral indices and rizYJ photometry. Right-hand figure: distribution in 4000Å-break versus J − 24 μm colour (upper panel) and in estimated dust attenuation A_g versus J − 24 μm colour (lower-left panel) or versus stellar mass (lower-right panel).
