Example of a magnetospheric accretion model image, produced with the MCFOST radiative transfer code. Shown here is the continuum-subtracted Brγ emission region of a purely axisymmetric rotating magnetosphere with no additional emission components. Channel line maps such as this can be used to compute artificial interferometric observables which we are then able to compare to real observational data. The image here specifically shows the line map for the −69 km s⁻¹ velocity channel.
