- Description:
- This database table contains the EXOSAT observation log. This is a complete list of all EXOSAT observations, observing modes, and principal investigators. The log can be used to find out which targets were observed by EXOSAT, who observed them, and the current state of the data analysis. The HEASARC revised this database table in August, 2005, in an effort to modernize its parameter names and add Galactic coordinates. This is a service provided by NASA HEASARC .

- EXOSAT TGS L and R Orders
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- Spectra obtained using the EXOSAT transmission grating spectrometer, TGS. There are two databases TGS and TGS2 as follows: <pre> * TGS - the grating spectra averaged over the positive and negative orders * TGS2 - the postive and negative orders kept separate </pre> TGS provides a better overview of the spectrum, and is quicker to use with a spectral fitting program. This is the default that most users will want to use. Once a user has become more expert and wants to see, for example, if a subtle feature is present in both halves of the grating spectra, the user can access TGS2. This is a service provided by NASA HEASARC .

- Description:
- The Faint Object Spectrograph (FOS) was one of the 4 original axial instruments aboard the Hubble Space Telescope (HST). The FOS was designed to make spectroscopic observations of astrophysical sources from the near ultraviolet to the near infrared (1150 - 8000 Angstroms). The instrument was removed from HST during the Second Servicing Mission in February 1997.

- Far Ultraviolet Explorer (FUSE) Observation Log
- Short Name:
- FUSE
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- NASA's FUSE (Far Ultraviolet Spectroscopic Explorer) spacecraft provided spectra in the far-ultraviolet portion of the electromagnetic spectrum (the wavelength range from 905 - 1180 Angstroms, or 90.5 - 118 nm), with a high spectral resolution of about 20000 (one wavelength point each 5 pm). FUSE was funded by NASA as part of its Origins program, and was developed in collaboration with the space agencies of Canada and France. It was operated for NASA by the Johns Hopkins University. FUSE was launched into orbit aboard a Delta II rocket on June 24, 1999 for a nominal mission of three years of operations. This table contains the FUSE Observation Log up to May 8, 2007, as archived at CDS in summer 2007. FUSE was formally decommissioned on October 18, 2007, following the failure of the last control wheel on the spacecraft in July 2007. More information about the FUSE Project can be found at NASA's Optical and Ultraviolet Archive (MAST) at <a href="http://archive.stsci.edu/">http://archive.stsci.edu/</a> and at the Johns Hopkins FUSE web site at <a href="http://fuse.pha.jhu.edu/">http://fuse.pha.jhu.edu/</a>. This database table was updated by the HEASARC in March 2009, superceding the previous versions of May 2007, May 2004, March 2005, and April 2006. It is primarily based on the CDS table <B/fuse>, specifically, the files fuse.dat, refs.dat and proposal.dat, but also contains additional information on proposal titles and bibliographic codes obtained from the MAST FUSE Archive. The HEASARC plans to update the bibliographic metadata for this table on a monthly basis as and when new information from the latter source becomes available.

- Publisher:
- Space Telescope Science Institute Archive
- Description:
- The Far Ultraviolet Spectroscopic Explorer (FUSE), launched on June 24, 1999, covers the 905-1187 Å spectral region and will obtain high resolution spectra of hot and cool stars, AGNs, supernova remnants, planetary nebulae, solar system objects as well as perform detailed studies of the interstellar medium. FUSE will be able to observe sources 10 000 times fainter than Copernicus, an early FUV mission, and has superior resolving power than the Hopkins Ultraviolet Telescope (HUT) and the Berkeley Spectrograph (BEFS) and the Tübingen Echelle Spectrograph (TUES) of the Orbiting Retrievable Far and Extreme Ultraviolet Spectrometers (ORFEUS). FUSE was planned for a 3 year lifetime with funding for an additional 2 years expected.

- Description:
- </pre><p>Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. <p>The data collected during the first 22 months of the nominal, five-year mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC), resulting into this second data release. A summary of the release properties is provided in Gaia Collaboration et al. (2018b). The overall scientific validation of the data is described in Arenou et al. (2018). Background information on the mission and the spacecraft can be found in Gaia Collaboration et al. (2016), with a more detailed presentation of the Radial Velocity Spectrometer (RVS) in Cropper et al. (2018). In addition, Gaia DR2 is accompanied by various, dedicated papers that describe the processing and validation of the various data products: Lindegren et al. (2018) for the Gaia DR2 astrometry, Riello et al. (2018) and Evans et al. (2018) for the Gaia DR2 photometry, Sartoretti et al. (2018), Soubiran et al. (2018), and Katz et al. (2018) for the Gaia DR2 spectroscopy (radial velocities), Holl et al. (2018) for the Gaia DR2 variability, Andrae et al. (2018) for the Gaia DR2 astrophysical parameters, Gaia Collaboration et al. (2018g) for the Solar-system objects, and Gaia Collaboration et al. (2018f) for the celestial reference frame. Four more papers present a glimpse of the scientific richness of the data in the areas of the Hertzsprung-Russell diagram (Gaia Collaboration et al. 2018a), the mapping of the kinematics and large-scale structure of the Milky Way (Gaia Collaboration et al. 2018e), parallaxes and proper motions of Milky Way satellite galaxies (Gaia Collaboration et al. 2018d), and variable stars in the colour-magnitude diagram (Gaia Collaboration et al. 2018c). In addition to the set of references mentioned above, this documentation provides a detailed, complete overview of the processing and validation of the Gaia DR2 data.
