Lambert, unit of luminance (brightness) in the centimetre-gram-second system of physical measurement.
Even after the above processing steps, images with no visible PCO and in which PCO would not be expected still showed on histogram analysis to have image areas with low but significant intensities of up to 15 units of brightness that contributed to elevated entropy scores.
The amplitudes of flares in a unit of average brightness of the star range from 1.3×10−3 to 8.5×10−2, and the bolometric energies of flares range from 2×1032 to 8×1035 erg.
It has a 200 lumen digital projector built-in, which is roughly equivalent to around 2,000 lumen with a lamp-powered home unit in terms of brightness.
Subtle patterns can be found on the lids, of the glossy models, with the palm rest mirroring the color of the PC adding a splash of brightness to the unit".
This device measures sky brightness in units of magnitudes per square arcsecond (magnitude is a measure of brightness, the lower the number the brighter the sky; square arcseconds is a measure of area, where one arcsecond is 1/3600 of a degree).
Photometry, a perception of brightness as seen by the human eye, is performed with a lux meter in units called lux.
Cutumba was a blaze of brightness.
Twisters of brightness against grey sky".
Saturday, an extra layer of brightness, Saturday brightness, like God opening a window in the sky.
