... The Chilled 3-chip Color CCD Camera C5810 was developed to provide real color imaging in low light level conditions. This camera incorporates 3 CCD chips coupled to a trichromatic beam splitter that reproduces real colors at all microscope intensities. ... Peltier elements are used to cool the CCDs to reduce thermal noise to minimal levels while fixed pattern noise such as illumination shading and any remaining thermal noise can be removed with the built-in image subtraction feature. ...

... Usually, H I is seen as bright emission against a darker background, but under the right viewing conditions, it can also be seen as dark absorption against a brighter background. In the case where the background is itself H I emission, the hydrogen is said to be self-absorbed, and the radiative transfer process is termed H I self-absorption (HISA). ...

... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...
