    Judd's uniform chromaticity space (UCS), with the Planckian locus and the isotherms from 1000 K to 10000 K, perpendicular to the locus. Judd calculated the isotherms in this space before translating them back into the (x,y) chromaticity space, as depicted in the diagram at the top of the article.

  3. Aberration (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Aberration_(astronomy)

    The relation with is : [0.000099365 rad / 2 π rad] x [365.25 d x 24 h/d x 60 min/h] = 8.3167 min ≈ 8 min 19 sec = 499 sec. This is possible since the transit time of sunlight is short relative to the orbital period of the Earth, so the Earth's frame may be approximated as inertial.

  4. Atmospheric correction - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_correction

    Atmospheric correction is the process of removing the scattering and absorption effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors. [ 1 ] [ 2 ] Atmospheric effects in optical remote sensing are significant and complex, dramatically altering the spectral nature of the radiation reaching the ...

  5. API gravity - Wikipedia

    en.wikipedia.org/wiki/API_gravity

    There are advantages to field testing and on-board conversion of measured volumes to volume correction. This method is detailed in ASTM D287. [4] The hydrometer method is a standard technique for directly measuring API gravity of petroleum and petroleum products. [5]

  6. Linear interpolation - Wikipedia

    en.wikipedia.org/wiki/Linear_interpolation

    Linear interpolation on a data set (red points) consists of pieces of linear interpolants (blue lines). Linear interpolation on a set of data points (x 0, y 0), (x 1, y 1), ..., (x n, y n) is defined as piecewise linear, resulting from the concatenation of linear segment interpolants between each pair of data points.

  8. Standard deviation - Wikipedia

    en.wikipedia.org/wiki/Standard_deviation

    If, instead of having equal probabilities, the values have different probabilities, let x 1 have probability p 1, x 2 have probability p 2, ..., x N have probability p N. In this case, the standard deviation will be σ = ∑ i = 1 N p i ( x i − μ ) 2 , where μ = ∑ i = 1 N p i x i . {\displaystyle \sigma ={\sqrt {\sum _{i=1}^{N}p_{i}(x_{i ...

    en.wikipedia.org/wiki/Molar_volume

    Change in volume with increasing ethanol fraction. The molar volume of a substance i is defined as its molar mass divided by its density ρ i 0: , = For an ideal mixture containing N components, the molar volume of the mixture is the weighted sum of the molar volumes of its individual components.
