quality flag of 4 indicates an unambiguous redshift identified with multiple features or the presence of the split  doublet.]{}

-   [Q=3.5: A quality flag of 3.5 indicates a high-confidence redshift based on a single line, with a very remote possibility of an incorrect identification. An example might be a strong, isolated emission line identified as H$\alpha$, where other identifications of the line are highly improbable due to the lack of associated lines or continuum breaks. This flag is typically only adopted for LRIS and MOSFIRE spectra.]{}

-   [Q=3: A quality flag of 3 indicates a high-confidence redshift with a low probability of an incorrect identification. An example might be the low signal-to-noise ratio detection of an emission line, possibly corrupted by telluric emission or absorption, identified as , but where the data quality is insufficient to clearly resolve the doublet.]{}

-   [Q=2/1: A quality flag of 2 indicates a reasonable guess, while a quality flag of 1 indicates a highly uncertain guess. Sources with these low confidence redshifts are not included in the data release.]{}

-   [Q=0: A quality flag of 0 indicates that no redshift could be identified. As described next, a code indicating the cause of the redshift
