I am attempting to convert the total power supplied by a physics journal into total radiative flux.

To provide background: The Ulysses probe was launched in the early 90s to investigate magnetospheric properties (i.e. electromagnetic emissions) on Jupiter.

Between 110 and 163 Jovian radii (69,173 km), the probe measured a total power of $1.1 \cdot 10^{8} - 5.6 \cdot 10^{8}$ W on the 27-48 keV band.

My method: A beginner of radiative processes, I simply converted joules to ergs and divided the resulting value by the average distance in cm. I suspect that there is a more accurate technique.
