NIST Ultraviolet Spectrum of Platinum Lamp

Spectrum of Platinum

Subject(s)
Content type(s)
Country
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.

HyperLeda

Leda

Subject(s)
Content type(s)
Country
HyperLeda is an information system for astronomy: It consists in a database and tools to process that data according to the user's requirements. The scientific goal which motivates the development of HyperLeda is the study of the physics and evolution of galaxies. LEDA was created more than 20 years ago, in 1983, and became HyperLeda after the merging with Hypercat in 2000

GOES Space Environment Monitor

Geostationary Operational Environmental Satellites SEM

Subject(s)
Content type(s)
Country
The GOES Space Environment Monitor archive is an important component of the National Space Weather Program --a interagency program to provide timely and reliable space environment observations and forecasts. GOES satellites carry onboard a Space Environment Monitor subsystem that measures X-rays, Energetic Particles and Magnetic Field at the Spacecraft.

Archives of programs and data for physics

Archives for physics

Subject(s)
Content type(s)
Country
>>>!!!<<< 2018-01-18: no data nor programs can be found >>>!!!<<< These archives contain public domain programs for calculations in physics and other programs that we suppose about will help during work with computer. Physical constants and experimental or theoretical data as cross sections, rate constants, swarm parameters, etc., that are necessary for physical calculations are stored here, too. Programs are mainly dedicated to computers compatible with PC IBM. If programs do not use graphic units it is possible to use them on other computers, too. It is necessary to reprogram the graphic parts of programs in the other cases.

MCHF/MCDHF Database

Multiconfiguration Hartree-Fock and Multiconfiguration Dirac-Hartree-Focbasek Data

Subject(s)
Content type(s)
Country
The MCHF/MCDHF database contains collections of transition data from different relativistic theories by different computational methods. For a few collections the Landé gJ factor is provided.

Handbook of Basic Atomic Spectroscopic Data

NIST Standard Reference Database 108

Subject(s)
Content type(s)
Country
This handbook is designed to provide a selection of the most important and frequently used atomic spectroscopic data in an easily accessible format. The compilation includes data for the neutral and singly-ionized atoms of all elements hydrogen through einsteinium (Z = 1-99).

POES Space Environment Monitor

Polar Orbiting Environmental Satellites

Subject(s)
Content type(s)
Country
The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth. The Earth's rotation allows the satellite to see a different view with each orbit, and each satellite provides two complete views of weather around the world each day. NOAA partners with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) to constantly operate two polar-orbiting satellites – one POES and one European polar-orbiting satellite called Metop. NOAA's Polar Orbiting Environmental Satellites (POES) carry a suite of instruments that measure the flux of energetic ions and electrons at the altitude of the satellite. This environment varies as a result of solar and geomagnetic activity. Beginning with the NOAA-15 satellite, an upgraded version of the Space Environment Monitor (SEM-2) has been flown.

Network for the Detection of Atmospheric Composition Change

NDACC

Subject(s)
Content type(s)
Country
The Network for the Detection of Atmospheric Composition Change (NDACC), a major contributor to the worldwide atmospheric research effort, consists of a set of globally distributed research stations providing consistent, standardized, long-term measurements of atmospheric trace gases, particles, spectral UV radiation reaching the Earth's surface, and physical parameters, centered around the following priorities.

NIST FLYCHK

Collisional-Radiative Code

Subject(s)
Content type(s)
Country
FLYCHK provides a capability to generate atomic level populations and charge state distributions for low-Z to mid-Z elements under NLTE conditions.

LEDAS

LEicester Database and Archive Service

Subject(s)
Content type(s)
Country
The Leicester Database and Archive Service (LEDAS) is an easy to use on-line astronomical database and archive access service, dealing mainly with data from high energy astrophysics missions, but also providing full database functionality for over 200 astronomical catalogues from ground-based observations and space missions. The LEDAS also allows access to images, spectra and light curves in graphics, HDS and FITS formats, as well as access to raw and processed event data. LEDAS provides the primary means of access for the UK astronomical community to the ROSAT Public Data Archive, the ASCA Public Data Archive and the Ginga Products Archive by its Archive Network Interface ARNIE.

Astrophysics Source Code Library

ASCL

Subject(s)
Content type(s)
Country
The Astrophysics Source Code Library (ASCL) is a free online registry for source codes of interest to astronomers and astrophysicists and lists codes that have been used in research that has appeared in, or been submitted to, peer-reviewed publications. The ASCL is citable by using the unique ascl ID assigned to each code. The ascl ID can be used to link to the code entry by prefacing the number with ascl.net (i.e., ascl.net/1201.001).
