Spectral Flux Density

(S, Flux Density)
(flux or power of radiation per unit area per unit wavelength)

The Spectral Flux Density is a measure of the flux passing through a unit area at a particular Wavelength.

Examples, e.g., for classifying Submillimeter Galaxies.

  • S850 - flux density at 850um.
  • S1.1 - flux density at 1.1mm.
