Solar coronal magnetic field strength at different heights in the corona estimated using various radio techniques (C. E. Alissandrakis & D. E. Gary 2021). The rectangular boxes labeled “S” and “B” represent the magnetic field strengths estimated from the ray-tracing simulations at ≈ 1.65 R_⊙ in the present work. They correspond to the discrete source (Section 4) and the background corona (Equation (13) and Table 2), at the above location, respectively. The extent of the boxes indicates the error in the estimates.
