Spectral fit with fado to a synthetic spectrum from Rebetiko corresponding to an instantaneous-burst age of 3 Myr. The input spectrum includes nebular line and continuum emission computed from the LyC photon output from the stellar component, whereby case B recombination and standard conditions for the gas were assumed. The fit was computed in the FCmode of fado with the SSP library Base ℱ. The meaning of the panels is identical to that in Fig. 3.
