To fit the low-J transitions from Figure 4, two models are constructed to determine if the secondary components are differentiable. One is of a point source (Section 3.3.2) and the other is of a circumplanetary disk (Section 3.3.3). Though the differences are too small to be discernible in our analysis, we do see that, given a massive enough planet, the circumplanetary disk’s signature ends up being wider and having smaller amplitude.
