Lines of the flow alongside the terminal lines defined by the maximum allowed field line. The terminal line is defined by an arbitrary percentage of error. While the percentage is the same for all physical quantities, in this case 5%, the angle where the model is valid takes different values depending on the physical quantity, and therefore corresponds to a different maximum field line. The lines, starting with the closest to the axis, are assigned to pressure, density, Mach number, radial velocity, and the radial magnetic field. The errors of speed, γu, and specific enthalpy remain significantly smaller than 5% in this region.
