- Description:
- Since its launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has triggered and located on average approximately two {gamma}-ray bursts (GRBs) every three days. Here, we present the third of a series of catalogs of GRBs detected by GBM, extending the second catalog by two more years through the middle of 2014 July. The resulting list includes 1405 triggers identified as GRBs. The intention of the GBM GRB catalog is to provide information to the community on the most important observables of the GBM-detected GRBs. For each GRB, the location and main characteristics of the prompt emission, the duration, peak flux, and fluence are derived. The latter two quantities are calculated for the 50-300keV energy band where the maximum energy release of GRBs in the instrument reference system is observed, and also for a broader energy band from 10 to 1000keV, exploiting the full energy range of GBM's low-energy [NaI[Tl)] detectors. Using statistical methods to assess clustering, we find that the hardness and duration of GRBs are better fit by a two-component model with short-hard and long-soft bursts than by a model with three components. Furthermore, information is provided on the settings and modifications of the triggering criteria and exceptional operational conditions during years five and six in the mission. This third catalog is an official product of the Fermi GBM science team, and the data files containing the complete results are available from the High-Energy Astrophysics Science Archive Research Center.

- The twenty-five year Lick planet search
- Short Name:
- J/ApJS/210/5
- Date:

- Description:
- The Lick Planet Search program began in 1987 when the first spectrum of {tau} Ceti was taken with an iodine cell and the Hamilton Spectrograph. Upgrades to the instrument improved the Doppler precision from about 10m/s in 1992 to about 3m/s in 1995. The project detected dozens of exoplanets with orbital periods ranging from a few days to several years. The Lick survey identified the first planet in an eccentric orbit (70 Virginis) and the first multi-planet system around a normal main sequence star (Upsilon Andromedae). These discoveries advanced our understanding of planet formation and orbital migration. Data from this project helped to quantify a correlation between host star metallicity and the occurrence rate of gas giant planets. The program also served as a test bed for innovation with testing of a tip-tilt system at the Coud\'e focus and fiber scrambler designs to stabilize illumination of the spectrometer optics. The Lick Planet Search with the Hamilton Spectrograph effectively ended when a heater malfunction compromised the integrity of the iodine cell. Here, we present more than 14000 velocities for 386 stars that were surveyed between 1987 and 2011.
1973. The Tycho-2 Catalogue
- ID:

- Title:
- The Tycho-2 Catalogue
- Short Name:
- I/259
- Date:
- 21 Oct 2021
- Publisher:
- CDS
- Description:
- The Tycho-2 Catalogue is an astrometric reference catalogue containing positions and proper motions as well as two-colour photometric data for the 2.5 million brightest stars in the sky. The Tycho-2 positions and magnitudes are based on precisely the same observations as the original Tycho Catalogue (hereafter Tycho-1; see Cat. <I/239>)) collected by the star mapper of the ESA Hipparcos satellite, but Tycho-2 is much bigger and slightly more precise, owing to a more advanced reduction technique. Components of double stars with separations down to 0.8 arcsec are included. Proper motions precise to about 2.5 mas/yr are given as derived from a comparison with the Astrographic Catalogue and 143 other ground-based astrometric catalogues, all reduced to the Hipparcos celestial coordinate system. Tycho-2 supersedes in most applications Tycho-1, as well as the ACT (Cat. <I/246>) and TRC (Cat. <I/250>) catalogues based on Tycho-1. Supplement-1 lists stars from the Hipparcos and Tycho-1 Catalogues which are not in Tycho-2. Supplement-2 lists 1146 Tycho-1 stars which are probably either false or heavily disturbed.

- The Tycho Reference Catalogue
- Short Name:

- Date:

- Publisher:
- CDS
- Description:
- The Tycho Reference Catalogue (TRC) contains high-quality positions and proper motions for 990182 stars of the Tycho Catalogue. The proper motions were derived from Tycho positions and Astrographic Catalogue positions reduced to the Hipparcos system. The median accuracy of the TRC position components is 40 mas at J1991.25. The median accuracy of the proper motion is about 2.5 mas/yr. Systematic errors are less than about 1.0 mas(/yr). The quality of the proper motions in TRC is assessed by comparison with the Hipparcos and Tycho Catalogues. Comparison with the recent ACT Catalogue which is based on an independent reduction of the same observations as used for constructing the TRC is reported.

- Publisher:
- CDS
- Description:
- The UCAC2 Bright Star Supplement (UCAC2 BSS) is meant to be used with the Second U.S. Naval Observatory CCD Astrograph Catalog (UCAC2, CDS Catalogue number <I/289>) to fill in the missing bright stars and yet-to-be observed northern regions of the UCAC2. In total 430,000 stars, mostly from the region north of +40 degrees declination, make up this supplementary data set. All astrometric data were extracted from either the Hipparcos Catalogue or the Tycho-2 Catalogue; photometric data were extracted from the Hipparcos, Tycho-2, and 2MASS catalogues. Cross references between the data sources are given.

- Publisher:
- CDS
- Description:
- United States Naval Observatory (USNO) Robotic Astrometric Telescope (URAT) Parallax Catalog south (UPCs) and north (UPCn). These data are based on the accepted paper for the Astronomical Journal (2018) by C. Finch, N. Zacharias, and W.-C. Jao, "URAT south parallax results: discovery of new nearby stars" (2018AJ....155..176F). The southern data are new, while the northern data contain a subset of the previously published UPC catalog after applying the more stringent selection criteria of the south data and supplementing the data with columns of the southern data. The previously published URAT Parallax Catalog (UPC) paper is: C. Finch and N. Zacharias (2016AJ....151..160F, Cat. J/AJ/151/160) (arXiv:1604.06739).
1977. The USNO-A2.0 Catalogue
- ID:

- Title:
- The USNO-A2.0 Catalogue
- Short Name:
- I/252
- Date:
- 21 Oct 2021
- Publisher:
- CDS
- 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.

- Description:
- The USNO-B1.0 is a catalog that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,045,913,669 objects derived from 3,648,832,040 separate observations. The data were taken from scans of 7,435 Schmidt plates taken from various sky surveys during the last 50 years. The catalog is expected to be complete down to V=21; the estimated accuracies are 0.2arcsec for the positions at J2000, 0.3mag in up to 5 colors, and 85% accuracy for distinguishing stars from non-stellar objects.

- Short Name:

- Publisher:
- CDS
- Description:
- The Carina Nebula is one of the most massive and active star-forming regions in our Galaxy and has been studied with numerous multiwavelength observations in the past five years. However, most of these studies were restricted to the inner parts (<=1 square-degree) of the nebula, and thus covered only a small fraction of the whole cloud complex. Our aim was to conduct a near-infrared survey that covers the full spatial extent (~5 square-degrees) of the Carina Nebula complex and is sensitive enough to detect all associated young stars through extinctions of up to A_V_~~6mag. We used the 4m Visible and Infrared Survey Telescope for Astronomy (VISTA) of ESO to map an area of 6.7 square-degrees around the Carina Nebula in the near-infrared J-, H-, Ks-bands.
