Table 3.
Constraints on Δα/α for the unification and dilaton models as well as for the general case with an atomic clocks prior (the clocks model), as reported in Clara & Martins (2020), for the various choices of primordial abundances used in the analysis.
| Abundances | Unification | Dilaton | Clocks |
|---|---|---|---|
| Baseline | 12.5 ± 2.9 | 19.9 ± 4.5 |
 |
| Null | 4.6 ± 3.8 | 5.8 ± 6.5 |
 |
| Extended | 12.5 ± 2.9 | 19.5 ± 4.5 |

Notes. The listed values are in ppm, and they correspond to the best fit in each case and to the range of values within Δχ2 = 4 of it.
