- Chandra X-ray Observatory
- Description:
- The Chandra X-ray Observatory is the U.S. follow-on to the Einstein Observatory and one of NASA"s Great Observatories. Chandra was formerly known as AXAF, the Advanced X-ray Astrophysics Facility, but renamed by NASA in December, 1998. Originally three instruments and a high-resolution mirror carried in one spacecraft, the project was reworked in 1992 and 1993. The Chandra spacecraft carries a high resolution mirror, two imaging detectors, and two sets of transmission gratings. Important Chandra features are: an order of magnitude improvement in spatial resolution, good sensitivity from 0.1 to 10 keV, and the capability for high spectral resolution observations over most of this range. The Chandra Source Catalog (CSC) includes information about X-ray sources detected in observations obtained using the Chandra X-ray Observatory. Release 2.0 of the catalog includes 317,167 point, compact, and extended sources detected in ACIS and HRC-I imaging observations released publicly prior to the end of 2014. Observed source positions and multi-band count rates are reported, as well as numerous derived spatial, photometric, spectral, and temporal calibrated source properties that may be compared with data obtained by other telescopes. Each record includes the best estimates of the properties of a source based on data extracted from all observations in which the source was detected. The Chandra Source Catalog is extracted from the CXC"s Chandra Data Archive (CDA). The CXC should be acknowledged as the source of Chandra data.

- Description:
- MCD is a database of atmospheric statistics compiled from Global Climate Model (GCM) numerical simulation of Martian atmosphere (<a href=http://www-mars.lmd.jussieu.fr>http://www-mars.lmd.jussieu.fr</a>). The GCM computes in 3D the atmospheric circulation and climate taking into account radiative transfer through the gaseous atmospheres and the dust and ice aerosols, includes a representation of the CO2 ice condensation and sublimation on the ground and in the atmosphere, simulates the water cycle (with modelling of cloud microphysics), the dust multisize particle transport, the atmospheric composition controlled by the photochemistry and the local non-condensible gas enrichment and depletion induced by CO2 condensation and sublimation, and has been extended into the thermosphere and to model ionospheric processes (due to chemistry). The database extends up to exobase (the top of the thermosphere, roughly at 300km in altitude); in addition to statistics on temperature, wind, pressure, radiative fluxes, it provides data such as atmospheric composition (including dust water vapor and ice content) and make use of 'dust and Extreme Ultra Violet (EUV) scenarios' to represent the variation of dust in the atmosphere and solar EUV conditions.

- Publisher:
- United States Naval Observatory, Flagstaff Station
- Description:
- The U.S. Naval Observatory (USNO) announces the release of the first version of the Naval Observatory Merged Astrometric Dataset (NOMAD). The 100 GB dataset contains astrometric and photometric data for over 1 billion stars derived from the Hipparcos, Tycho-2, UCAC2, and USNO-B catalogs for astrometry and optical photometry, supplemented by 2MASS near-infrared photometry. For each unique star the "best" astrometric and photometric data are chosen from the source catalogs and merged into a single dataset. A sequence of priorities is followed and NOMAD contains flags to identify the source catalogs and gives cross-reference identifications. This first release of NOMAD is not a compiled catalog; that is, if a star is identified in more than 1 of the above mentioned catalogs, only 1 catalog entry is chosen. Thus the local and global systematic errors of the various source catalogs will be present in this version of NOMAD. All source catalogs astrometric data are on the International Celestial Reference System within the limitations of the source catalogs. For more information and data retrieval see our homepage www.nofs.navy.mil/nomad.

- Description:
- Since 1973, the 18-cm lines of the OH radical have been systematically observed in a number of comets with the Nançay radio telescope. This allowed an evaluation of the cometary water production rates and their evolution with time, as well as a study of several physical processes: the excitation mechanisms of the OH radio lines, the expansion of the cometary atmospheres, their anisotropy in relation with non-gravitational forces, the Zeeman effect in relation with the cometary magnetic field. The Nançay observations of 53 cometary apparitions between 1982 and 2009 are now organized in this database.

- Description:
- The NASA/IPAC Extragalactic Database (NED) provides a comprehensive fusion of multi-wavelength data for hundreds of millions of objects located beyond the Milky Way galaxy. As new observations are published in NASA mission archives, journal articles and sky survey catalogs, they are cross-identified with prior measurements and integrated in a unified database. Numerous derived quantities are also provided to facilitate scientific research. For more information see http://ned.ipac.caltech.edu/

- Publisher:
- United States Naval Observatory, Flagstaff Station
- Description:
- USNO-A2.0 is a catalog of 526,280,881 stars, and is based on a re-reduction of the Precision Measuring Machine (PMM) scans that were the basis for the USNO-A1.0 catalog. The major difference between A2.0 and A1.0 is that A1.0 used the Guide Star Catalog (Lasker et al. 1986, see Cat. <I/220>) as its reference frame whereas A2.0 uses the ICRF as realized by the USNO ACT catalog (Urban et al. 1997, see Cat. II/246>). A2.0 presents right ascension and declination (J2000, epoch of the mean of the blue and red plate) and the blue and red magnitude for each star. Usage of the ACT catalog as well as usage of new astrometric and photometric reduction algorithms should provide improved astrometry (mostly in the reduction of systematic errors) and improved photometry (because the brightest stars on each plate had B and V magnitudes measured by the Tycho experiment on the Hipparcos satellite). The basic format of the catalog and its compilation is the same as for A1.0, and most users should be able to migrate to this newer version with minimal effort. (1 data file).

- Publisher:
- United States Naval Observatory, Flagstaff Station
- Description:
- USNO-B is an all-sky catalog that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,042,618,261 objects derived from 3,643,201,733 separate observations. The data were obtained from scans of 7435 Schmidt plates taken for the various sky surveys during the last 50 years. USNO-B1.0 is believed to provide all-sky coverage, completeness down to V=21, 0.2" astrometric accuracy at J2000, 0.3 mag photometric accuracy in up to five colors, and 85% accuracy for distinguishing stars from nonstellar objects. A brief discussion of various issues is given here, but the actual data are available from the US Naval Observatory Web site and others.

- Publisher:
- Paris Astronomical Data Centre
- Description:
- The ephemeris were produced by simulating the ejection of meteoroids from the sunlit hemisphere of cometary nuclei, typically from 0 to 3 au, followed by the propagation of orbits of meteoroids in the Solar System, taking into account the gravity of the Sun, the 8 planets, Pluto, and the Moon, as well as the radiation pressure and the Poynting-Robertson drag. Note that asteroid parent bodies were considered as active (i.e. comet-like bodies) even if they are not active today. The showers are predicted when a planet enters a large enough set of meteoroids, at a distance less than typically 0.01 au.
