This tab sets the parameters of the spherical sources in the 3D model. It is possible to add as many sources as desired.

​

Several options can be set here: the position of the source, its inner and outer radii, the inner density, temperature, and molecular abundance, as well as the mass of the central object (which can be gridded).

​

On the right part of the interface, a pop-up menu allows to accurately describe the physical profiles (density, temperature, molecular abundance) of the source, using several regions to define them.
