Scaling relations between emission-line luminosity and SFR. Uncorrected/de-reddened [O ii] luminosity against SFR in the upper and lower panel, respectively. Error-bars in the lower panel are omitted to enhance clarity (typical errors in the top left corner). The color-coding of the individual measurements corresponds to A_V as indicated by the color bar. The solid black lines show the best-fit scaling relations from Eq. (1). The gray-shaded area denotes the 1σ scatter in the relation − 0.45 dex in the upper and 0.19 dex in the lower panel.
