- Illumination maps of 67P
- Short Name:

- Centre de Données de la Physique des Plasmas(CDPP)
- Description:
- Illumination by the Sun of each face of the comet 67P/Churyumov-Gerasimenko based on the shape model CSHP_DV_130_01_LORES_OBJ.OBJ. The service provides the cosine between the normal of each face (in the same order as the faces defined in the shape model) and the Sun direction; both numerical values and images of the illumination are available. Each map is defined for a given position of the Sun in the frame of 67P (67P/C-G_CK). Longitude 0 is at the center of each map. The code is developed by A. Beth, Imperial College London, UK and the service is provided by CDPP (http://cdpp.eu). Acknowlegment: The illumination models have been developed at the Department of Physics at Imperial College London (UK) under the financial support of STFC grant of UK ST/N000692/1 and ESA contract 4000119035/16/ES/JD (Rosetta RPC-PIU). We would also like to warmly thank Bernhard Geiger (ESA) for his support in validating the 2D-illumination maps.

- Publisher:
- Paris Astronomical Data Centre - USN
- Description:
- Decametric radio observation from Nancay decameter array. The Nancay Decameter Array (NDA) at the Station de Radioastronomie de Nancay (SRN) is a phased array of 144 "Teepee" helicoidal antenna, half of which being Right Handed (RH) polarized and the other half being Left Handed (LH) polarized. Four receivers are currently connected to the NDA, sampling data in spectral ranges within 5 to 80 MHz.

- NOMAD Catalogue
- Short Name:

- Date:

- 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.

- Title:
- Predictions of stellar occultations by the main planetary satellites
- Short Name:
- voccdb.epn_core
- Date:

- Publisher:
- Paris Astronomical Data Centre
- Description:
- The VOccDB database provides prediction and parameters of stellar occultations by the main planetary satellites. Observations of a stellar occultations help to better determine the size and the shape of the occulting body, as well as its astrometric position at the milli-arcsecond level precision. Only the main moons of giant planets Jupiter, Saturn, Uranus and Neptune are considered in the event prediction database. Predictions are provided over period 2023-2032, up to visual magnitude 12 for the biggest satellites, and magnitude 14 for other satellites. For each stellar occultation event prediction, the database provides circumstances and observational data, date and timing of the occultation, star position and magnitude, excepted duration, etc.

- Publisher:
- US Naval Observatory
- Description:
- The USNO Flagstaff Station Image and Catalogue archive provides access to digitized images of the major Schmidt photographic surveys of the sky (POSS-I, POSS-II, SERC-J, SERC-R, SERC-EJ, SERC-ER, AAO-R etc.) and to astrometric catalogues derived from these data, including USNO-A2, USNO-B1 and NOMAD. The site provides catalogue data, finding charts, image data and a merge of the three.

- 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).
