>>>!!!<<< 2019-12-04: The repository is no longer available >>>!!!<<< Presented here are excitation cross sections measured for a select number of transitions using the Merged Electron-Ion Beams Energy Loss (MEIBEL) experiment. This is a collaboration of JILA and the Multicharged Ion Research Facility (MIRF) at Oak Ridge National Laboratory (ORNL), where the apparatus is located. Since there exist a nearly infinite number of transitions in multicharged ions we have chosen a few that serve as benchmarks for theoretical efforts. Of particular interest are forbidden transitions which are often dominated by dielectronic resonances whose positions and magnitudes are difficult to predict theoretically.
The ACE Science Center (ASC) serves to facilitate collaborative work on data from the Advanced Composition Explorer (ACE) spacecraft and to ensure that those data are properly archived and publicly available. The collaborators served are not limited to ACE project-funded investigators.
In February 1986 the NIST measurements were communicated to appropriate astronomers for use in ground-based testing and calibration programs for the GHRS, and in 1990 the NIST group published the new wavelengths for about 3000 lines in the Supplement Series of the Astrophysical Journal. The full report on the NIST measurements in the form of a complete and detailed atlas of the platinum/neon spectrum presented in this special issue of the Journal of Research of NIST will be highly useful to a wide range of scientists.

The primary interaction of low-energy x rays within matter, viz. photoabsorption and coherent scattering, have been described for photon energies outside the absorption threshold regions. These tables are based on a compilation of the available experimental measurements and theoretical calculations. For many elements there is little or no published data and in such cases it was necessary to rely on theoretical calculations and interpolations across Z. In order to improve the accuracy in the future considerably more experimental measurements are needed.
<<<!!!>>> NVO - National Virtual Observatory is closed now <<<!!! >>> The National Virtual Observatory (NVO) was the predecessor of the VAO. It was a research project aimed at developing the technologies that would be used to build an operational Virtual Observatory. With the NVO era now over, a new organization has been funded in its place, with the explicit goal of creating useful tools for users to take advantage of the groundwork laid by the NVO. To carry on with the NVO's goals, we hereby introduce you to the Virtual Astronomical Observatory http://www.usvao.org/
>>>!!!<<< 2019-12-03: The repository is no longer available >>>!!!<<< Please use https://www.cfa.harvard.edu/amp/ampdata/kurucz23/sekur.html The atomic line data used in this database are taken from Bob Kurucz' CD-ROM 23 of spectroscopic line calculations. The database contains all lines of the file "gfall.dat" with the following items for each line: Wavelength; loggf; element code; lower level: energy, J, configuration; upper level: energy, J, configuration; gamma r; gamma s; gamma w; reference code. CD-ROM 23 has all the atomic line data with good wavelengths in one large file and in one file for each species. The big file is also divided into 10 nm and 100 nm sections for convenience. Also given are hyperfine line lists for neutral Sc, V, Mn, and Co that were produced by splitting all the energy levels for which laboratory data are available (only a small fraction).
This database gives values of the basic constants and conversion factors of physics and chemistry resulting from the 2002 least-squares adjustment of the fundamental physical constants as published by the CODATA Task Group on Fundamental Constants and recommended for international use by CODATA.
The Atomic Data for Astrophysics server provides links to basic atomic data required for calculation of the ionization state of astrophysical plasmas and for quantitative spectroscopy.
Earthdata powered by EOSDIS (Earth Observing System Data and Information System) is a key core capability in NASA’s Earth Science Data Systems Program. It provides end-to-end capabilities for managing NASA’s Earth science data from various sources – satellites, aircraft, field measurements, and various other programs. EOSDIS uses the metadata and service discovery tool Earthdata Search https://search.earthdata.nasa.gov/search. The capabilities of EOSDIS constituting the EOSDIS Science Operations are managed by NASA's Earth Science Data and Information System (ESDIS) Project. The capabilities include: generation of higher level (Level 1-4) science data products for several satellite missions; archiving and distribution of data products from Earth observation satellite missions, as well as aircraft and field measurement campaigns. The EOSDIS science operations are performed within a distributed system of many interconnected nodes - Science Investigator-led Processing Systems (SIPS), and distributed, discipline-specific, Earth science Distributed Active Archive Centers (DAACs) with specific responsibilities for production, archiving, and distribution of Earth science data products. The DAACs serve a large and diverse user community by providing capabilities to search and access science data products and specialized services.
