| The radiative energy of a source can be given either in relative terms via some [[~:..:magnitude|magnitude scale]] or in absolute terms via some measure of [[~:..:radiative_qauntities|radiative quantities]]. | The radiative energy of a source can be given either in relative terms via some [[~:..:magnitude|magnitude scale]] or in absolute terms via some measure of **radiative quantities**. |

| Recall from the discussion on [[~:..:what_the_detector_measures|what detectors measure]] that after calibration of a raw light image to account for the effects of the detector as well as the effects of the atmosphere, the counts that remain associated with each pixel are assumed to be proportional to the amount of radiant energy that fell into the pixel during integration time. | Recall from the discussion on [[wiki:astronomy:observational_astronomy:measurements:what_the_detector_measures|what detectors measure]] that after calibration of a raw light image to account for the effects of the detector as well as the effects of the atmosphere, the counts that remain associated with each pixel are assumed to be proportional to the amount of radiant energy that fell into the pixel during integration time. |
