Flux computation example , Nancay Decametric Array :

25 MHz , 100 data units , source in beam axis
calibrated with 50.71 dB 300 kelvin calibrator , ~ 165 data units
Flux = NoiseTemperature*Boltzman/Bandwidth/EffectiveArea
NoiseTemperature = 10^(DataUnits*0.046) kelvin
Boltzman = 1.38E-23 joule/kelvin
Bandwidth = 1E5 hertz
EffectiveArea at 25MHz ~ 3.3E3 meter^2
area is proportional to cosine^2(angle from line of sight to antenna axis) , antenna axis point to 20 degrees south of zenith
Flux = 3.98E4*1.38E-23/1E5/3.3E3 = 1.66E-27 watt/hertz/meter^2

12:  About the origin of Jupiter's magnetic field

I take note of the links to 26 presentations given at the Juno Europlanet Meeting 2018:

https://www2.le.ac.uk/departments/physics/people/leighfletcher/ras-juno-europlanet-meeting-2018

The presentation by Chris Jones, University of Leeds in the United Kingdom, shows 16 slides about Jupiter's magnetic field, slide 3 describes the origin of Jupiter and Saturn magnetic fields in the very different metallic regions of hydrogen and helium:
