plotted against FWHM. We separated the sample into z> 3 (red triangles) and z ≤ 3 (blue diamonds). The best-fit power laws for the two samples are FWHM (km s-1) 
(z ≤ 3, blue) and FWHM (km s-1) 
(z> 3, red). The slopes are consistent with each other and with the slope derived from the full sample in Fig. 1.
