Image Details
Caption: Figure 7.
Example AGEL spectra of varying redshift quality flags. The top row is a deflector spectrum from X-shooter with redshift quality flag = 2, and the bottom row is a deflector spectrum from X-shooter with quality flag=1. grz 25″ × 25″ DECaLS images are shown in the left column with north oriented up and east left. Key spectral features used in the redshift measurement are shown with dotted orange lines. The slit position is shown as an orange rectangle overlaying the DECaLS image.
