- Description:
- The INTEGRAL observatory (Winkler et al. 2003, A&A, 411, L1) was launched in October 2002. The spectrograph SPI (Vedrenne et al. 2003, A&A, 411, L63) consists of 19 Germanium detectors and is capable of imaging in the 20 - 8000 keV band because of a coded mask. Part of the core program of the INTEGRAL mission is a study of the Galactic Centre, the Galactic Centre Deep Exposure (GCDE).<p> The SPI significance map is based on the public GCDE data and uses data in the 20 - 40 keV energy range. The analysis of the data was done using the SPIROS software (Skinner & Connell 2003, A&A, 411, L123). This software uses the 'Iterative Removal of Sources' technique in order to find the most significant sources. In the output significance map the sources found in this process are put on top of the residual map as points with a FWHM of 1 degree. <p> Current data respresent the combination of all public observations as of September 1, 2004.

- Description:
- The International Ultraviolet Explorer (IUE) performed spectrophotometry at high (0.1-0.3 Å) and low (6-7 Å) resolution between 1150 Å and 3200 Å. The data cover a dynamic range of approximately 17 astronomical magnitudes: -2 to 10 for high dispersion; -2 and 14.9 for low dispersion. Over 104,000 ultraviolet spectra were obtained with IUE between January 26, 1978, and September 30, 1996.

- Description:
- This table contains the IRAM 30-m single-dish telescope observation log. The Institut de Radio Astronomie Millimetrique (IRAM) was founded in 1979 and is operated as a French-German-Spanish collaboration. Its partner institutes are the CNRS (Centre National de la Recherche Scientifique, France), the MPG (Max Planck Gesellschaft, Germany), and the IGN (Instituto Geografico Nacional, Spain). The principal activity of IRAM is the study of cold matter (molecular gas and dust) in the solar system, in our Galaxy, and out to cosmological distances, in order to determine its composition, density, mass, temperature, and kinematics. IRAM operates two observatories at millimeter wavelengths which are open to the international astronomical community: the 30-m single-dish telescope on Pico Veleta (2850 m), Spain, and the six-antenna interferometer on the Plateau de Bure (2550 m) in France. Both sites are at high altitude to reduce the absorption by water vapor. The observatories are supported by the IRAM offices and laboratories in Granada and Grenoble. The observation log included here concerns the 30-m single-dish telescope, and summarizes the observations made there since September 30, 2009. The observation log for the the six-antenna interferometer on the Plateau de Bure in France is also available as the HEASARC database table <a href="/W3Browse/ground-based/irampdblog.html">IRAMPDBLOG</a>, and the observation log for NOEMA (the NOrthern Extended Millimeter Array), the successor to the Plateau de Bure observatory, is available as the HEASARC database table <a href="/W3Browse/ground-based/iramnoelog.html">IRAMNOELOG</a>. For more information on IRAM, see <a href="http://www.iram-institute.org/">the IRAM home page</a>. This table was originally ingested by the HEASARC in January 2011. It is based on the CDS table B/iram/, files 30m.dat and 30m_pi.dat. It was last updated in September 2020, based on an updated version of these tables which were also obtained from the CDS.

The observation log included here concerns NOEMA, the NOrthern Extended Millimeter Array, and summarizes the observations made there. NOEMA is the successor to the Plateau de Bure observatory. During its history, the observatory at the Plateau de Bure underwent several track extensions, received additional antennas (all of 15-m diameter and of similar construction to the first ones) and technical upgrades. From a three-antenna interferometer with a maximum baseline of 288 meters in 1988, it has evolved to a eight-antenna array with baselines up to 760 meters in 2016. With the inauguration of the seventh antenna in September, 2014, the observatory started its transformation into NOEMA. More information about NOEMA is <a href="http://www.iram.fr/IRAMFR/GILDAS/doc/html/noema-intro-html/noema-intro.html">available at the IRAM web site</a>. The observation log for the 30-m telescope is available as the HEASARC database table <a href="/W3Browse/ground-based/iram30mlog.html">IRAM30MLOG</a>, and the observation log for the Plateau de Bure Interferometer is available as the HEASARC database table <a href="/W3Browse/ground-based/irampdblog.html">IRAMPDBLOG</a>.

- Description:
- The IRAS data include all data distributed as part of the IRAS Sky Survey Atlas. Data from the four IRAS bands are shown as individual surveys in SkyView. Users should be aware that IPAC does not encourage the use of data near the ecliptic plane as they feel that contribution from local cirrus emission is significant. <p> The data are distributed in sets of 430 maps. Each map covers approximately 12.5x12.5 degrees, and the map centers are offset by 5 degrees so that there is a 2.5 degree overlap. IPAC has processed to a uniform standard so that excellent mosaics of the maps can be made. Users should be cautious of data in saturated regions. Known problems in the analysis mean that data values are unlikely to be correct. Note that IPAC has optimized the processing of these data for features of 5' or more although the resolution of the data is closer to the 1.5' pixel size. <p> There are occasional pixels in the IRAS maps which are given as NULL values. Unless these are explicitly trapped by user software, these data will appear as large negative values. SkyView ignores these pixels when determining the color scale to display an image. <p> Essentially the entire sky is covered by the survey. However there are a few regions not surveyed and the data values in these regions are suspect. These are given to users as delivered from IPAC. Provenance: NASA IPAC/Jet Propulsion Laboratory.

- Description:
- IRSF (InfraRed Survey Facility) is located at Suhterland, South Africa and the survey project started since Nov. 2000 in the near infrared (J, H, Ks) bands. The facility (SIRIUS camera and 1.4-m IR telescope) is easy both for operation and data-reduction, owing to its simplicity. The instrument has been producing numerous scientific data every clear night for the last four and half years under friendly collaboration between Nagoya Univ-Kyoto Univ-NAOJ (Japan) and SAAO (South Africa).

- Description:
- Ion data from the Plasma Composition Experiment on ISEE-1 consist of a combination of (a) velocity moments for the four principal magnetospheric ion species H+, He++, He+, and O+, calculated in two different ways (using two different sets of assumptions) and covering the 0.01-0.1 and 0.1-16 keV/e energy ranges, (b) energy-angle spectra for the same four ions plus O++, covering the 0.01-17.9 keV/e range, and (c) mass spectra (<1 amu/e to about 150 amu/e) for four energy ranges, all derived once per each complete energy-mass scan cycle of the instrument, or once each 1- to 20-minute interval, depending on mode of operation, as well as (d) "total ion" moments, derived once per energy scan and assuming total count rate is due to H+ ions (0.1-16 keV).
