The host contribution is defined here as the flux ratio α(λ) = Ihost(λ)/Itot(λ) and is computed by dividing a spectrum of the host with the VLT spectrum including the TDE (after proper absolute flux calibration). Solid lines represent smoothed versions for each dataset, using a Savitzky-Golay filter. The location of prominent emission features is marked with vertical dashed lines and regions of significant telluric absorption are shown as shaded regions (their location differs for each TDE due to their different redshifts).
