... Virtually all detectors and telesco pes are sensitive to only a particular range of frequencies or wavelengths. ... Flux per unit wavelength or frequency So in practice, when we measure how much radiation we receive from some object, we usually mean the energy at some particular frequency, not the integral of the energy over all frequencies (which would be the bolometric brightness). ... But imaging data at UV, optical and IR wavelengths often uses a different approach: broad-band imaging. ...
