Table B.1.

Attributes of the discminer model for the 12CO intensity channel maps of the disk around J1604. PA is the position angle of the semimajor axis of the disk on the redshifted side, R the cylindrical radius, and D0 = 100 au a normalization constant for the line properties. The (down-sampled) pixel size of the model is 8.8 au.
