Greetings,
As a sanity check, has anyone else tried converting Solar Flux Units to a
Noise Temp in Kelvin?
I believe the formula comes out as:
T = (SFU*10^-22 * lam^2 * freq) / k
where
T = Noise Temp in Kelvin
SFU = observed Solar Flux Unit
lam = wavelength in meters at freq
freq = operating frequency
k = Boltzmann's constant 1.38*10^-23
Thanks,
Lee-KU4OS
