Using XML-Schema to Model Data from Present and Future Astronomical Databases
XML (eXtensible Markup Language) has now become an almost inescapable tool for the exchange of formatted data over the World Wide Web and is now... -
Power Spectrum for the Distribution of Galaxies on the Sphere
A method of Gorski of calculation of the power spectrum for CMB for incomplete COBE data set is applied to the distribution of galaxies on the... -
Wide-Field X-Ray Monitoring as a Data Source for the Virtual Observatory
We refer on novel X-ray telescopes with high sensitivity as well as large field of view of order of 1 000 square degrees or even more. The results... -
Laplacean Ideology for Preliminary Orbit Determination and Moving Celestial Body Identification in Virtual Epoch
Any CCD frames with stars or galaxies or clusters and other images must be studied for a searching of moving celestial objects, namely asteroids,... -
The World Space Observatory (WSO/UV) Archive: Requirements for Interoperation
