| SiII(126.0) | 126.04 | 1.037 | +103 |
| SiIII(120.7) | 120.65 | 1.008 | −21 |

Notes. The second column lists the rest-frame wavelength of the transition. The third column is the ratio between the metal transition and the Lyα transition, where λ1 is the greater of the two wavelengths. The last column gives the apparent radial distance difference between the Lyα and metal absorption corresponding to vanishing physical separation, at λObs. = 410 nm.
