FWG versus log P. Black points indicate the FWGs derived from L and T_eff (from the SED fitting) and stellar mass in the present paper. Black open squares are LMC objects, filled squares indicate SMC objects. Blue symbols indicate the CCs (filled squares) and one T2C (filled triangle) in EB systems. The black line is a fit to the black points, minus the two marked outliers. The red circles indicate FWGs from HR spectroscopy (open circles indicate LMC, filled circles indicate SMC), Light blue filled squares indicate FWGs of 20 MC CCs from da Silva et al. (2022), while the green points indicate the FWGs for the same 20 objects from Luck (2018; open squares indicate that only one spectrum is available in Luck 2018, filled squares indicate that five or more spectra are available).
