Temperature differences between the elliptic orbits at perihelion and the time-averaged radius (﹩{\bar{r}}_{t}﹩) (top row), the time-averaged flux (﹩{\bar{r}}_{{tF}}﹩) (middle row), and the effective thermal radius (r _T ) equivalent orbits (bottom row) for three depths: surface (left column), 1 m (middle column), and 10 m (right column) for all the a, e couples.
