Next: Passbands Up: Instrument configuration and Previous: Storage format . ... We need two kinds of information for filters and detectors: physical information about the instrument itself, and logical information about the way it is represented in data files -- for example, the codes used to identify filter positions. ... In addition to information about the instrument itself, the reduction program needs to know the structure of the data in their table file (see section , ``Observational data''). ...

... Judged by their instrumental profiles, spectrometers fall into two basic classes---Lorentzian and Gaussian---with many other line profile functions (sinc functions, Voigt functions, Airy functions, etc.) falling into one of these two categories in some limit. We demonstrate that the Rayleigh, Sparrow, and Houston resolution criteria are of limited use compared to the ``equivalent width'' of the line profile. ... Rayleigh criterion. ... All of these functions have continuous higher derivatives. ...

... The general scientific activity of the stuff is not a static phenomena, but mainly it lies in the direction, reflected in the famouse book by Ya.B.Zeldovich and I.D.Novikov "Relativistic Astrophysics". ... They can be separated into three main branches: "discology" (prof. N.I.Shakura, N. Ketsaris and grad.student G.V. Lipunova); astrophysics of neutron stars, evolution of close binaries and related problems (prof. V.M.Lipunov , prof. K.A.Postnov , drs. ...

... 2002 June 1 . NGC 2266: Old Cluster in the New General Catalog . ... Explanation: The New General Catalog of star clusters and nebulae really isn't so new. ... Dreyer's work was successful and is still important today as this famous catalog continues to lend its "NGC" to bright clusters, galaxies, and nebulae. Take for example this star cluster known as NGC 2266 (item number 2,266 in the NGC compilation). ... With an age of about 1 billion years, NGC 2266 is old for a galactic cluster. ...

For non-spherical isotropic particles, the classic variant of the RDG approximation does not include the anisotropy of the shape and hence does not give the correct Rayleigh limit, say, for small ellipsoids. ... We call this variant a modified RDG approximation (MRDG). ... First, the MRDG leads to the correct Rayleigh limit. ... The second approach to generalization of the RDG is connected with the use of the Born iterations for the scattering integral equation [ 95 , 124 , 132 , 264 ]. ...
