Graphical representation of the 2-zone MCMax3D model. Zone 1, in red, corresponds to a UID component with an outer radius of 1 AU. Zone 2 corresponds to the outer disk resolved by the ALMA observations. Zone 2 has been subdivided into zones 2a, 2b, and 2c, corresponding to the resolved inner disk (RID, zone 2a), inner ring (zone 2b), and second and third rings (zone 2c). This subdivision was created for the purpose of locally altering some model parameters. For the purpose of modeling the surface density of the disk, however, zone 2 is treated as a single region. The inner and outer radii for each zone are given in Tables 1 and 2.
