Spectra and images of two dual quasar candidates. In each row the left sub-panel shows the spectra and the right sub-panel presents the DESI Legacy Imaging Surveys DR9 grz composite image. Top : dual quasar candidate of groupid = 9333. Spectrum of image A is from SDSS DR16 and that of image B is from DESI DR1; automated spectral redshifts are z_A = 0.7239 and z_B = 0.7201. The angular separation is 13.17 arcsec, corresponding to a projected distance of 95.01 kpc; the velocity difference is 661.56 km s⁻¹. Bottom : dual quasar candidate of groupid = 26644. Spectrum of image A derives from DESI DR1 and image B from SDSS DR16 with automated spectral redshifts z_A = 2.3028 and z_B = 2.2938. The angular separation is 11.61 arcsec, giving a projected distance of 96.51 kpc; the velocity difference is 818.04 km s⁻¹.
