LzLCS sources on the RC–SFR relation at 3 GHz top panels and 6 GHz in the bottom panels. The left (right) panel shows the UV-based (Hβ-based) SFRs for the LzLCS sources. In all panels, the blue points represent detections in the corresponding band and the orange points represent the 3σ upper limits for non-detections. The solid black line is plotted for the standard RC–SFR relation with α_nth = −0.8. The dotted, dashed and dotted dashed lines are for different values of α_nth from flat (−0.3) to very steep (−2), respectively. The red solid line represents the RC_th–SFR relation from Eq. (3). In all these cases, we have used a fixed value of T_e = 10 000 K.
