Comparison between SFR derived from SED modelling (SFRSED) and those measured from IR+UV observations (SFRIR + UV) for VC875, shown for different model parametrisations. From top to bottom: (first) the fiducial model using the Charlot & Fall (2000) dust attenuation law and a delayed SFH with a recent variation episode; (second) the same, but without the recent variation episode; (third) the fiducial model without ALMA dust luminosity constraints; (fourth) the Calzetti et al. (1994) attenuation law model. Blue points represent individual pixels, with error bars corresponding to the 16th and 84th percentiles of the SED-derived SFR distribution (see Sect. 3.1). Red arrows indicate upper limits. Black points show region-averaged SFR values computed using the B23 method. The dashed line indicates the one-to-one relation, and dotted lines mark the ±50% range.
