Redshift flags.
| zQ | Meaning |
|
|
|
| −2 | Z_ERR> 0.005(1 + Z) or ZWARNING≠0 or 4 |
| −1 | CLASS = “STAR” |
| 1. | one line at low S/N |
| 1.5 | two lines at low S/N |
| 2. | one line at high S/N |
| 2.5 | three or more lines at low S/N |
| 3. | one line at high S/N and at least one line at low S/N |
| 3.5 | [Oii] 3728 at high S/N |
| 4. | two lines at high S/N |
| 4.5 | three or more lines at high S/N |
| 0 | none of the conditions above are met |
|
|
|
| zCont | meaning |
|
|
|
| 2.5 | magnitude u or g or i or z< 19.5 |
| 2. | ′′ <20 |
| 1.5 | ′′ <20.5 |
| 1 | >3 lines with the continuum detected at S/N 10 |
| 0.5 | >3′′ S/N 8 |
| 0 | none of the conditions above are met |
Notes. Low and high S/N correspond to 3 ≤ S/N< 5 and 5 ≤ S/N, respectively. The [Oii] 3727, 3729 emission line doublet is a special case. It is sometimes observed as a blended doublet, sometimes only as a single line. The CLASS = “STAR” category means that the best fit of the pipeline is based on a stellar template.
