... The reduction system of observations FADPS (description in Russian) (Flexible Astronomical Data Processing System) for data of wide-band receivers of the first observation cabin of the radio telescope RATAN-600 had been created under the Unix-like operational system DEMOS for computers of the SM-1420-type (PDP/11) in 1987 for observation analysis and estimates of coordinates and flux densities of radio sources. ...

... This generalization gives rise to the four-dimensional time-frequency-scale-chirprate (TFSC) parameter space. ... We then consider the use of multiple analyzing wavelets/windows, first to generalize Thomson's method of spectral estimation to the TF plane, and then to further generalize this result to the chirplet transform. ... We generalize autocorrelation and cross-correlation by using the signal itself (or another signal) as a ``mother chirplet''. ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...

Description and Technical Details . In 1980s two medium-size horizontal solar telescopes 50/35000 cm with large spectrographs Czerny-Turner made by Carl Zeiss Jena were installed in the Ondњejov observatory. The Czerny-Turner-spectrographs in the Ondњejov observatory called HSFA1 and HSFA2 according to the German name Horizontal-Sonnen-Forschungs-Anlage ("horizontal device for solar research") have been explored for more than two decades. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

... the data are described accurately enough to allow an unambiguous interpretation of the data, as well as a comprehension of the context in which the data were acquired and/or processed; a single ascii file, named ReadMe , is designed for this role. the data are in a format which allows their usage by tools currently in usage in our discipline -- normally flat ascii files ; other formats can be accepted, but are converted into flat files. ...

... Configuration The dictionary accepts one obligatory parameter - RULES, which has to be set to the file describing parsing rules and output recipes. ... Each non-empty line is either a comment (when started with '#' symbol), or a conversion rule, and in the latter case has to contain whitespace-separated pattern and output recipe. Currently, pattern has to match the _integer_ (one, two or more) number of input tokens; they will be replaced with a single one. ...
