Fig. 4

The dimensionless reflection fraction Rf, is estimated as a function of the corona height H (in units of Rg) and the bulk velocity β = υ/c. The dashed line corresponds to the reflection fraction Rf = 1.0. The color bar represents the dimensionless reflection fraction, with the minimum and maximum being 0.1 and 6.4, respectively.
