| O | > 1.0 | > 0.83 | <0.60 | <0.83 |
| Ne | > 1.43 | > 1.30 | <0.55 | <1.30 |
| Mg | > 0.62 | > 0.48 | <0.22 | <0.48 |
| Si | > 2.70 | > 1.60 | <1.30 | <1.60 |
Notes. (1) Constraints on the ratio (X/Fe)/(X/Fe)LMC. (2) Constraints on the lower limit (X/Fe)/(X/Fe)LMC−Δ(X/Fe), where Δ(X/Fe) is the uncertainty of the abundance ratio. (3) Constraints on the upper limit (X/Fe)/(X/Fe)LMC + Δ(X/Fe).
