Comparison of Hα hybridised with F335M_PAH, F770W, F1000W and F1130W and the attenuation-corrected Hα obtained using the Balmer decrement. The dashed blue line is the best linear fit while the white circles represent a binned average. The slope and intercept of the best-fit power law together with the scatter with respect to the best model are reported on the top left corner. The solid black line represents the one-to-one relation.
