Description:
This table contains the IRAM Plateau de Bure Interferometer 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 Plateau de Bure Interferometer (PdBI) and summarizes the observations made there between December 1, 1990, and March 31, 2017, inclusive. No observations were done by the PdBI during the periods 1999-Sep-30 to 2000-Dec-03 and 2006-Sep-25 to 2007-Jan-18 (installation of the new receiver), notice. 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 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 November 2005. It is based on the CDS table B/iram/, files pdbi.dat and pdbi_pi.dat. It was last updated in July 2019, based on an updated version of these tables which were also obtained from the CDS.

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:
These hardcopy plots were provided as a supplement to the digital data from the Plasma Composition Experiment (NSSDC data set 77-102A-12I). A subset of the data in the digital data files is plotted in graphical form in a series of booklets, one booklet for each month of data. There are two pages of graphs for each day, and each page has a stack of 7 panels showing the variation of different parameters during the course of a 12-hour Universal Time interval. Panel 1 (top panel) shows densities of He++, He+, and O+ ions, and the "total" ion density (per cubic meter); Panel 2 shows He++/H+ density ratio; Panel 3 shows ion "thermal" energy (eV); Panel 4 shows "thermal" energy density multiplied by 2/3 along with the magnetic pressure (eV/m^3) and field strength (nT); Panel 5 shows ion drift speed (meters/sec) in the GSE X-Y plane; Panel 6 shows magnetic field elevation angle (degrees) relative to the GSE X-Y plane; Panel 7 shows ion drift angle and the magnetic longitude angle.

Description:
This database is the ISO (Infrared Space Observatory) Observation Log of Validated Data. ISO is an ESA (European Space Agency) project with instruments funded by ESA member states (especially the PI countries of France, Germany, the Netherlands and the United Kingdom), and with the participation of ISAS (Japan) and NASA (USA). ISO operated from November 1995 till May 1998, almost a year longer than expected. As an unprecedented observatory for infrared astronomy, able to examine the cool and hidden places in the Universe, ISO successfully made nearly 30,000 scientific observations. The ISO data can be retrieved from the ISO Data Archive (&lt;a href="http://iso.esac.esa.int/ida/"&gt;http://iso.esac.esa.int/ida/&lt;/a&gt;), which is available at the ISO Data Centre (&lt;a href="http://iso.esac.esa.int/"&gt;http://iso.esac.esa.int/&lt;/a&gt;), and comprises about 150,000 observations, including calibration, parallel mode and serendipitous observations. The present catalog contains all observations performed in standard observing modes exempt from technical problems; special flags indicate calibration observations. The catalog gives observation details and provides links to quick-look images depicting the data and to observation-specific documentation. The ISO helpdesk can be reached at &lt;a href="http://iso.esac.esa.int/esupport/"&gt;http://iso.esac.esa.int/esupport/&lt;/a&gt; This online catalog was last updated by the HEASARC in September 2004 based on the machine-readable table &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VI/111/isolog.dat.gz"&gt;https://cdsarc.cds.unistra.fr/ftp/cats/VI/111/isolog.dat.gz&lt;/a&gt; obtained from the CDS data center.

Publisher:
NASA/GSFC HEASARC
Description:
This IUE (International Ultraviolet Explorer) Observation Log contains a summary of all IUE Newly Extracted Spectra (INES), which resulted from a post-processing effort at VILSPA. It was constructed by using verified data from the IUE Final Archive Master Catalog. The observations cover the whole life of the IUE satellite, from March 1978 to September 1996. This online catalog was ingested by the HEASARC in August 2004 based on the machine-readable table VI/110/inescat.dat obtained from the CDS data center. In May 2020, the program_id values of &quot;\&quot; were changed by the HEASARC to nulls for improved database compatibility. This is a service provided by NASA HEASARC .

Publisher:
NASA/GSFC HEASARC
Description:
Launched in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission measures X-ray polarization from compact objects such as neutron stars and black holes, which serve as laboratories for exploring extreme gravitational and magnetic fields. With its imaging capabilities, IXPE will also map the magnetic-field structure of a few extended sources such as supernova remnants and pulsar wind nebulae. This table contains a list of (a) unobserved targets that are planned for observation by IXPE in the future and (b) IXPE observations which have been processed and successfully validated by the IXPE team. The data from these observations may or may not be public and the user should check the value of the public_date parameter to determine the status of a specified data set. Only those ObsIDs which have a public_date in the past will have data publicly available. Observations with a public_date parameter value which is either blank or a date in the future have been ingested into the HEASARC archive but will remain encrypted until their public date. This contents of this database table are generated by the IXPE Team and updated regularly with new observations. These updates are then delivered to the HEASARC and ingested into the HEASARC database in a timely fashion. Note that some parameters have been added and are populated by the HEASARC. This is a service provided by NASA HEASARC .
