Radial profile of the coronal density model constrained by densities from SDO/AIA and SOHO/LASCO. In blue, the plane-parallel solution reproduces the active region, (Eq. (7)), and in red, the spherical-symmetric solution reproduces the quiet Sun (Eq. (6)). The combined model in orange (Eq. (8)) is used to replace the missing data in the range 1.3−2.5 R⊙.
