Best-fitting parameters for the J1604 disk in total intensity in scattered light.
| Parameter | Unit | H2 band | H3 band | K1 band | K2 band | L′ band |
|---|---|---|---|---|---|---|
| θinc(a) | o | 6 | 6 | 6 | 6 | 6 |

Notes. (a)θinc was fixed as inferred from the dust continuum (Dong et al. 2017). (b)θPA was fixed as inferred from the 12CO intensity channel maps of the disk (Stadler et al. 2023). (c)Offset between ring center and star. Δx and Δy (Millar-Blanchaer et al. 2015) are expressed in units of instrument pixels, and they are fixed for specific bands. For the H2 band, we employed the best-fitting model from the H3 band, for the K2 band, we used the best-fitting result from the K3 band, and for the L′ band, no offset adjustments were applied.
