Comparisons between the SFR from CIGALE and the literature using the u-band. Left panel: SFR derived from the relation given in Hopkins et al. (2003) using the u-band. Right panel: SFR derived from the calibrated relation given in Davies et al. (2016) using the u-band and the old population decontamination from the u-g color. While the calibration of Hopkins et al. (2003) is in good agreement with CIGALE (mean of 0.07 dex and scatter of 0.08 dex for VIPERS, 0.15 and 0.09 dex for GSWLC), the decontamination from the old stellar population luminosity proposed by Davies et al. (2016) leads to an underestimation of the SFR for VIPERS (0.18 and 0.06 dex) at high SFR, and to a strong underestimation for GSWLC (0.42 and 0.22 dex).
