Projection of the FP onto the M_* coordinate against the observed M_*. In the top panel we have used the SFR derived from the Hβ flux, the metallicity using the Tremonti et al. (2004) calibration and the Lara-López et al. (2013a) parametrisation. The orange dots are the Lockman-SpReSO SFGs, the red crosses are the Oi et al. (2017) data and the blue contours at the bottom are the OSSY data. The middle panel shows the same, but with the IR-derived SFR. In the lower panel we show the recalibration of the FP using the OSSY data with IR information to obtain a calibrated FP with the L_TIR-derived SFR. A more detailed discussion is given in the text.
