Spiral models and associated fit parameters.
| Spiral type | Equation | r0 | b | Pitch angle | χ2 |
|---|---|---|---|---|---|
| Logarithmic | r = r0exp(bθ) | −3184 ± 164 au | −0.5175 ± 0.0185 | arctan(b) = −27.4° | 17.8 |
| Archimedean | r = r0 + bθ | −1712 ± 32 au | 337.9 ± 10.5 au | arctan(b/r) = −19.8 → −46.6° | 8.9 |
