Century Dictionary and Cyclopedia
    • n radiance Brightness shooting in rays or beams; hence, in general, brilliant or sparkling luster; vivid brightness.
    • n radiance Radiation.
    • n radiance Synonyms Radiance, Brilliance, Brilliancy, Effulgence, Refulgence, Splendor, Luster. These words agree in representing the shooting out of rays or beams in an Impressive way. Radiance is the most steady; it is generally a light that is agreeable to the eyes: hence the word is often chosen for corresponding figurative expressions: as, the radiance of his cheerfulness; the radiance of the gospel. Brilliance represents a light that is strong, often too strong to be agreeable, and marked by variation or play and penetration: as, the brilliance of a diamond or of fireworks. Hence, figuratively, the brilliancy of the scene at a wedding; the radiance of humor, the brilliancy of wit. Brilliance is more often literal, brilliancy figurative, Effulgence is a splendid light, seeming to fill to overflowing every place where it is—a strong, flooding, but not necessarily intense or painful light: as, the effulgence of the noonday sun; the effulgence of the attributes of God. Hence a courtier might by figure speak of the effulgence of Queen Elizabeth's beauty. Befulgence is often the same as effulgence, but sometimes weaker. Splendor, which is more often used figuratively is, when used literally, about the same as refulgence. Luster is the only one of these words which does not imply that the object gives forth light; luster may be used where the light is either emitted or reflected, but latterly more often reflected: as, the luster of silk. Luster is generally, like brilliance, a varying light, but it may be simply two or three degrees weaker than splendor. For comparison with glisten, glitter, etc., see glare, v. i.

It may be noted that whereas ZD’s maps represent intensity while ours are radiance.

In order to make quantitative comparison, the U I BA radiance maps of the five regions have been integrated over the same corresponding regions as imaged by ZD, to get I(UIBM SX ).

One of the parameters while modelling out the continuum from the MSX radiance in band A, is β , the dust emissivity index.
Spatial distribution of emission in Unidentified Infrared Bands from Midcourse Space Experiment Survey
ISOCAM data (hence MSX based UIB radiance estimates can be calibrated well); The above validates our assumption regarding emissivity law for interstellar dust grains and is self consistent with the assumed proportionality of UIB emission between the bands A and C of MSX.
Spatial distribution of emission in Unidentified Infrared Bands from Midcourse Space Experiment Survey
The correlation may be a result of spatial averaging over regions with different excitation details. – the numerical value of the ratio of UIB radiances obtained from MSX and ISOCAM is an important information for understanding relative strengths of UIBs.

In other regions, such as the short-wavelength part of the N-band, the telescope background dominates over the atmospheric radiance, and the benefit of a high site derives mainly from the lower ambient temperature.
