| Bailey & Williams (1988) | 0.9 < λ > 3.5 | Aλ/AV ∝ λ − α |
| Cardelli et al. (1989) | 0.35 < λ < 0.9 | Aλ / AV = fA(1 / λ, 7) + fB(1 / λ, 7) / RV |
| 0.9 < λ < 3.5 | Aλ / AV = C0·(1 / λ)α + C1·(1 / λ)α/RV | |
| Fitzpatrick & Massa (1990) | 0.11 < λ < 0.3 | 5-parameter model |
| Fitzpatrick (1999) | λ > 0.11 | RV tabled Aλ / AV |
| Indebetouw et al. (2005) | 1.25 < λ < 5. | log (Aλ/AV) = fA(log (λ), 2) |
Notes. (a) Polynomials fA(x,N) and fB(x,N): x variable, N polynomial order; C0 and C1 constants; RV = AV / EB − V.
