SFR_norm − L_X correlation in L_X bins, for different redshift intervals (z < 0.5, 0.5 < z < 1.2 and z > 1.2). Left, middle, and right panels: full sample, absorbed population, and unabsorbed population, respectively. The dashed line corresponds to the star-forming main sequence. Trends are similar in all redshift bins. Median SFR and L_X values are presented. The error bars represent the 1σ dispersion of each bin.
