full width at half maximum in a sentence

Examples

1. The WFC contained two coded aperture cameras operating in the 2 to 30 keV ( 320 to 4, 800 aJ ) range and each covering a region of 40 x 40 degrees ( 20 by 20 degrees full width at half maximum ) on the sky.
2. Assuming an exponential decay probability for the core hole in the time domain ( \ propto \ exp {-t / \ tau } ), the spectral function will have a Lorentzian shape, with a FWHM ( Full Width at Half Maximum ) \ Gamma given by:
3. This characteristic mainly reflects itself in a low Gaussian spectral distribution, the value of L c is inversely proportional to the spectral width, BW, so that the full width at half maximum ( FWHM ) of the power spectral density can be related to L c through the equation
4. where " t D " is the ion drift time, " ?t D " is the Full width at half maximum, L is the tube length, E is the electric field strength, Q is the ion charge, k is Boltzmann s constant, and T is the drift gas temperature.
5. However, to figure out how " long " it took the photons and baryons to decouple, we need a measure of the width of the PVF . The WMAP team finds that the PVF is greater than half of its maximal value ( the " full width at half maximum ", or FWHM ) over an interval of 115, 000 years.
6. where " x " 0 is the location parameter, specifying the location of the peak of the distribution, and ? is the scale parameter which specifies the half-width at half-maximum ( HWHM ), alternatively 2? is full width at half maximum ( FWHM ) . ? is also equal to half the interquartile range and is sometimes called the probable error.
7. Among the properties listed above, the light output is the most important, as it affects both the efficiency and the resolution of the detector ( the efficiency is the ratio of detected particles to the total number of particles impinging upon the detector; the energy resolution is the ratio of the full width at half maximum of a given energy peak to the peak position, usually expressed in % ).
8. The width of the photoluminescence peak represents the heterogeneity in size dispersion of the quantum dots, where a large size dispersion will lead to broad emission peaks, and tight size-dispersion will lead to narrow emission peaks, often quantified by the full width at half maximum ( FWHM ) value . eFluor Nanocrystals are specified at d " 30nm FWHM for the CdSe nanocrystals, and d " 70nm FWHM for the InGaP eFluor 700 nanocrystals.
9. where " f r " is the resonant frequency, ? " f " is the resonance width or full width at half maximum ( FWHM ) i . e . the bandwidth over which the power of vibration is greater than half the power at the resonant frequency, " ? r " = 2 " f r " is the angular resonant frequency, and ? " ? " is the angular half-power bandwidth.
