Ratio between the SFR derived using UV and Hβ luminosity as a function of the EW(Hβ). We note that typically galaxies with lower EW show a higher UV-based SFR compared to Hβ based SFR. We also overplot the stellar population synthesis models from Schaerer (2003) for a single burst model in solid lines, and continuous star-formation in dashed lines. The different colours blue, orange, green, and red represent the different metallicities corresponding to Z = 0.02 (solar), 0.008, 0.004, and 0.001, respectively.
