Lick/IDS indices for the UDG spectra and stacked GC spectra in Å.
| Hβ | Mg b | Fe 5270 | Fe 5335 | ⟨Fe⟩ | [MgFe]′ | |
|---|---|---|---|---|---|---|
| UDG | 2.21 ± 0.21 | 1.61 ± 0.17 | 1.69 ± 0.20 | 1.57 ± 0.25 | 1.63 ± 0.16 | 1.64 ± 0.11 |
| GCs | 2.65 ± 0.16 ± 0.19 | 0.97 ± 0.15 ± 0.22 | 1.07 ± 0.18 ± 0.18 | 1.08 ± 0.18 ± 0.30 | 1.08 ± 0.13 ± 0.23 | 1.02 ± 0.10 ± 0.14 |
Notes. The first errors represent statistical uncertainties measured from the stacked spectra. Also listed is the scatter obtained from bootstrapping the GCs that end up in the stack.
