Example Sentences
- "Such sources usually attain brilliance by high current densities in small volumes. The total energy output may therefore be less than a greatly extended source of low steradiancy."
- "The geometry of the cone θ and the irradiance at the image of the carbon block were used to determine the absolute steradiancy of the energy in the cone θ as a radiometer calibration value."
- "[…] steradiancies seen by the instrument during calibration were between 45 and 55 percent higher than the calculated average steradiancies […]"
