Summary plot with the correlations between the LyC absolute photon escape fraction () and the main UV spectral properties derived in this work: R(H I), R(LIS), W_H I, W_LIS and E_B−V (from top to bottom and left to right, respectively). Black thick error bars comprise the running median values and 0.16 and 0.84 quantiles of the parameters as a function of . The individual measurements are shown in the background through gray (LzLCS) and red (literature) symbols. Error bars at the top of the panels represent the median 1σ uncertainty of each parameter, based on individual errors.
