We would like to announce the release of Version 2.0 of the CHIANTI database for astrophysical spectroscopy. The additions and corrections to the database have been described in a paper `CHIANTI - an atomic database for emission lines, III - Continuum radiation and extension of the ion database' by E. Landi, M. Landini, K.P. Dere, P.R. Young, H.E. Mason and has been published in Astronomy and Astrophysics Supplement Series, 135, 339 ,1999, (Paper III). ... Beryllium sequence . ... Boron sequence . ...

The database contains references to the papers, data files and links to the Internet resources related to measurements and calculations of the optical constants in the wavelength interval from X-rays to radio domain. ... References to some useful books and reviews on the subject (e.g. the classical handbooks edited by E.D.Palik) and links to Internet collections of optical constants and personal WWW pages with related software were also placed in the database. You have arrived at our welcome page. ...

... Previous: Background Fluctuation Analysis from the Multiscale Entropy . ... A new measure of information is defined which is based on noise modeling and incorporates resolution scale. Properties of this measure are discussed. ... Additionally it allows for image noise modeling, and subsequent noise removal. ... Hence information- and entropy-based processing technologies will be necessary for the effective design and implementation of large, future generation, image databases. ...

... Panchuk V.E. Database "Stellar Spectra" consists of following main units: . ... obtained with various modifications of high resolution echelle-spectrometers at the 6-m telescope. ... Using the spectra obtained at BTA in combination with high resolution echelle-spectrometers LYNX and PFES , Chentsov E.L., Klochkova V.G. and Panchuk V.E. prepare now the next spectral atlas. ... The CATALOGUE of spectral photoplates obtained at the Main Stellar Spectrograph of the 6m telescope. ...

... All the parameters provided in this database have been obtained using the the MIRIAD ( Sault et al. 1995 ) task MBSPECT . MBSPECT makes a spectrum of the velocity (or frequency) axis of a cube. The spectrum is beam-weighted, over the width specified, for the other image axes. ... Robust parameters are calculated by using an algorithm which minimises the mean absolute deviation of the flux-weighted velocities. mask= This specifies the x-axis ranges to be excluded from any continuum fit. ...

... India (1999) xx, PINTofALE: Package for the Interactive Analysis of Line Emission V.Kashyap & J.J.Drake Center for Astrophysics, Cambridge, MA 02138, USA Abstract. ... It is based on a modular set of IDL tools that interact with an atomic database and with observational data. ... The package has been extended to handle analysis of high­resolution X­ray spectra that will be obtained with the Chandra X­Ray Observatory. Key words: X­rays, X­ray Spectroscopy, Stellar Coronae, Analysis Methods 1. ...

This JAVA interface gives the possibility for working with the radio emission data of radio sources in clusters of galaxies from the Cluster database. ... For this, after loading the document with optical (or radio) data for the requested cluster, click on [ radio spectra (1.2 or 1.1)] in the top line of the document and then choose interface version which is compatible with your Internet-browser. ... For more information about the JDK support in the browsers see Java for browsers . ...
