Current state

The JPDOC gives access to 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 the radio domain. The materials being considered are:

• amorphous/glassy/crystalline silicates of different kinds;
• silicon, SiO, crystalline/fused SiO$_2$;
• metals: Fe, Mg and others;
• oxides: FeO, Fe$_2$O$_3$, Fe$_3$O$_4$, MgO, Al$_2$O$_3$, MgAl$_2$O$_4$;
• sulfides: FeS, MgS, SiS$_2$;
• carbides: SiC, FeC, TiC;
• carbonaceous species: diamonds, graphite, coals, kerogens, HAC, glassy/amorphous carbon, PAH and so on;
• organics: tholin, ``organic refractory'', etc.;
• ices: H$_2$O, CO, CO$_2$, NH$_3$, HCN, etc. and their mixtures;
• FeSi, MgCO$_3$ and others.

The database contains more than 1000 references to the papers, reports, dissertations where the refractive index, reflectivity, transmittance, etc. were derived. It also gives references to useful books and reviews on the subject. Data accessible via the JPDOC are mainly those measured in the laboratory of the AIU Jena and supplemented with data freely available in the internet. The database also provides links to internet collections of optical data files and personal WWW pages with relevant software and includes some other useful information. The first version of the JPDOC was described in [1]. In the following years (1999-2001) only minor improvements were made. All the time the site was rather well visited - on average about 5 visitors a day and all together over 5000 visits for 3 years - and many visitors found the database helpful. That encouraged us to make essential updates in 2002 - we increased by about 25% the number of references to papers (not only to the recent ones) in physical and astronomical journals as well as to books and reviews, opened access to more data from Jena Laboratory, connected new pages presenting recently calculated low-temperature Rosseland and Planck mean opacities, included new materials (FeSi, MgCO$_3$, etc.), gave more links to other internet resources (incl. Ioffe Institute site, Database of Optical Properties, etc.), and presented some more graphical illustrations and information about the physical properties of the materials.
