Spectral in a sentence

Spectral absorbance is related to spectral optical depth by: : : where *A ν is the spectral absorbance in frequency; *A λ is the spectral absorbance in wavelength.

The spectral device makes use of spectral technology to develop advanced image sensor chips for 3D machine vision and spectral analysis.

Each star is assigned a spectral class from the older Harvard spectral classification and a luminosity class using Roman numerals as explained below, forming the star's spectral type.

There is a rather abrupt onset of X-ray emission around spectral type A7-F0, with a large range of luminosities developing across spectral class F. Altair is spectral type A7V and Vega is A0V.

To utilize UV frequency combs containing a million closely spaced spectral lines for spectroscopy applications, the researchers needed a method capable of achieving high spectral resolution—beyond the capabilities of existing spectrometers.

Because of this, and because the primaries in color printing systems generally are not pure themselves, the colors reproduced are never perfectly saturated spectral colors, and so spectral colors cannot be matched exactly.

By extending the spectral information of a perturbed sample, spectral analysis is simplified and resolution is enhanced.

Class Y seeAlso Artist's impression of a Y-dwarf Brown dwarfs of spectral class Y are cooler than those of spectral class T and have qualitatively different spectra from them.

In some cases spectral lines are well separated and distinguishable, but spectral lines can also overlap and appear to be a single transition if the density of energy states is high enough.

It has a period of 4.4 days;sfn its components are two massive hot blue stars, one a blue supergiant of spectral type O7.5-8 Iab, while its companion is a slightly cooler, less evolved and less luminous supergiant of spectral type O9.7Ib.

It is in a 1000-year orbit with a pair of stars, Da and Db, a yellow-white main sequence star of spectral type F7V and a red dwarf of spectral type M3V.

Red supergiants are cooler and redder than dwarfs of the same spectral type, and stars with particular spectral features such as carbon stars may be far redder than any black body.

Spectral power distribution Characteristic spectral power distributions (SPDs) for an incandescent lamp (left) and a fluorescent lamp (right).

Spectroscopy The general spectral type of Rigel as B8 is well-established and it has been used as a defining point of the spectral classification sequence for supergiants.

The short-term stability is measured by four main parameters: Allan variance (the most common one specified in oscillator data sheets), phase noise, spectral density of phase deviations, and spectral density of fractional frequency deviations.

This color is only an approximation of spectral indigo, since actual spectral colors are outside the gamut of the sRGB color system.

Added 100% of Aether dealt as Fire and 34 Fire damage modifiers for Spectral Binding.

Another flick looking to pack a sequel punch, The Nun II places Taissa Farmiga’s Sister Irene back in the habit and facing off once more with a terrifying spectral counterpart.

Her spectral could be summoned through a magical pebble that was gifted to Laeral Silverhand.

In addition, for the first time this year military personnel will practice operation of spectral control cells, whose role is to formulate a situational picture in the field of spectrum warfare.
