Redshift vs. W1-band magnitude. Filled red circles and filled blue triangles represent the 861 type 1 AGNs used in this study, identified from DESI DR1 and H. Shim et al. (2013), respectively. The gray dashed contours present the distribution of redshifts and W1-band magnitudes of SDSS DR14 quasars for comparison.
