Comparison of different extinction models: we measured HST photometric data points (red squares) in 0.2″ radius apertures; positions for the three examples shown here are indicated in the left panel. To these we fitted a synthetic STARS spectrum which was reddened using different reddening prescriptions: screen extinction (black), mixed extinction (grey), and the Calzetti et al. (2000) reddening law (magenta). We also overplot our SINFONI spectrum (blue), scaled to the HST 2.22 μm data point (absolute SINFONI flux at 2.2 μm shown as blue diamond). As can be seen, the Calzetti et al. (2000) reddening law provides the best fit to the data.
