Gray intensity

If an image has a very low gray intensity, a high clip limit p makes its histogram flatter and the image becomes brighter, even if noise can be more highlighted. 

Quicklime is usually white of varying intensity, depending on chemical purity some species possess a slight ash-gray, buff, or yellowish cast. Invariably quicklime is lighter in color than the limestone from which it is derived. Hydrated limes, except for hydrauHc and impure hydrates, are extremely white in color, invariably whiter than their quicklimes.

Solid symbols represent experimental data after subtraction of the spectrum corre-ponding to the pure polymer. Solid curves represent a three-component fit. Broken curves represent the individual fitted components, (b) Relative Raman intensities of the fitted profiles for the ( Aj, SO,) anion mode for this system, plotted against square root of the salt concentration, solvated ions ion pairs , triple ions, (c) The molar conductivity of the same system at 293 K.

Cyanazin (h/ f 5-10) appeared as gray, terbutylazin (h/ f 20-25) as violet and anilazin (h/Jj 35-40) as pale blue chromatogram zones (Fig. 1). The intensity of the spots increased during one hour but did not change thereafter. The detection limits for all three substances were 300 ng per chromatogram zone. These amounts could also readily be detected visually. 

Images were acquired with 5-s exposure time after having fixed the focus. The total intensity of fluorescence was estimated by calculations the integral of the gray-level histogram. 

Figure 6.6 Vibrational coherence on a pNB-adsorbed TiO2(110) surface, (a) The raw SH intensity, (b) the modulated component, (c) the Fourier-transformed spectrum, the gray lines show the transformed spectrum. The spectrum simulated with Lorentzian functions is overlaid with broken lines. The pNB-adsorbed surface was irradiated in air with p-polarized pump (8mjcm ) and p-polarized probe (8mjcm ) pulses of a 550-nm wavelength.

Fig. 8.16 Fe Mossbauer spectra of [Fe2 (PMAT)2](BF4)4-DMF at selected temperatures. At 298 K, the only quadrupole doublet is characteristic of iron(II) in the HS state. SCO from HS to LS occurs at one Fe(II) site of the dinuclear complex at ca. 225 K. The second Fe(II) site remains in the HS state, but feels the spin state conversion of the neighboring atom by local distortions communicated through the rigid bridging ligand, giving rise to a new quadrupole doublet (dark gray), i.e., HS in [HS-LS], in the Mossbauer spectrum. The intensity ratio of the resonance signals of HS in [HS-LS] to that of LS (black) in [HS-LS] is close to 1 1 at all temperatures (from [32])...

FIGURE 15.6 Gel image of the data in Fig. 15.4, where the density of the plot is proportional to the logarithm of the fluorescence intensity observed in each cycle. The data are plotted as a gray scale for low intensity components and a blue-green-yellow-red scale for the most intense components. 

Fig. 1. Gray scale rendering of the non-LTE abundance correction for varying metal-licity, for the grid of atmospheric parameters explored (with our standard choice for the collisions with hydrogen). Brighter parts of each plot correspond to larger non-LTE corrections, with intensity scaled as shown by the bar on the right hand side (dex units). The corrections refer to the absorption line of interest around 9100 A...
