spectrum has definitions from the field of physics
1
[ noun ] (physics) an ordered array of the components of an emission or wave

Used in print

(Cornell H. Mayer, "Radio Emission of the Moon...)

The observed intensity of the radio_emission of Venus is much higher than the expected thermal intensity , although the spectrum indicated by measurements at wave_lengths near 3 cm and 10 cm is like that of a black_body at about 600 ` K .

This result suggests a very high_temperature at the solid surface of the planet , although there is the possibility that the observed radiation may be a combination of both thermal and non thermal components and that the observed spectrum is that of a black_body merely by coincidence .

For the case of Jupiter , the radio_emission spectrum is definitely not like the spectrum of a black-body radiator , and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non thermal components .
