Comparison of four L_144 MHz–SFR calibrations derived from LOFAR observations at 144 MHz. For an easier comparison we use the calibrations obtained without the stellar mass dependence: log(L_144 MHz) = 22.221+1.058log(SFR) (Smith et al. 2021), log(L_144 MHz) = 22.024+1.019log(SFR) (Das et al. 2024), log(L_144 MHz) = 22.06+1.017log(SFR) (Gürkan et al. 2018), and log(L_144 MHz) = 22.24+1.08log(SFR) (Best et al. 2023). To better highlight the differences between calibrations, the plot shows only the region with high L_144 MHz and SFR. When needed, the SFR was converted to the initial mass function of Chabrier (2003) using the corrections provided in Madau & Dickinson (2014).
