- Description:
- The AllWISE program extends the work of the successful Wide-field Infrared Survey Explorer mission (WISE; Wright et al. 2010, AJ, 140, 1868) by combining data from the cryogenic and post-cryogenic survey phases to form the most comprehensive view of the mid-infrared sky currently available. AllWISE has produced a new Source Catalog and Image Atlas with enhanced sensitivity and accuracy compared with earlier WISE data releases. Advanced data processing for AllWISE exploits the two complete sky coverages to measure source motions for each Catalog source, and to compile a massive database of light curves for those objects. WISE is a National Aeronautics and Space Administration (NASA) Medium Class Explorer mission that scanned the sky methodically in the 3.4, 4.6, 12 and 22 #m mid-infrared bandpasses (hereafter W1, W2, W3 and W4) in 2010 and 2011. The 40 cm WISE telescope and payload equipped with four 1024x1024 pixel focal plane detector arrays were cooled by a dual-stage solid hydrogen cryostat. WISE carried out its 4-Band (or Full) Cryogenic survey from 2010 January 7 to 2010 August 6, observing the sky 1.2 times with all four detectors operating at full sensitivity. After the hydrogen ice in the outer cryogen tank evaporated, WISE surveyed an additional 30% of the sky during its 3-Band Cryo phase, with the W1 and W2 detectors operating at near full sensitivity, and the W3 focal plane operating at reduced sensitivity. The NEOWISE Post-Cryo phase (Mainzer et al. 2011 ApJ, 731, 53), funded by the NASA Planetary Division, started on 2010 September 29 after cryogen in both tanks was exhausted, and continued until 2011 February 1. NEOWISE Post-Cryo observations covered 70% of the sky with W1 and W2 detectors operating at near full sensitivity. Images and extracted source data from each of the three survey phases were release separately in the March 2012 All-Sky Data Release, the June 2012 3-Band Cryo Data Release, and the May 2013 NEOWISE Post-Cryo Release.

- Description:
- The WISE 3-Band Cryo Data Release products are comprised of data taken during the mission's 3-Band Cryo survey phase. This phase covers the time following the exhaustion of solid hydrogen in the WISE payload outer cryogen tank, while the detectors and telescope were still cooled by the inner cryogen tank. During this time, WISE's W1, W2 and W3 bands were operational and continued to acquire useful data, but the W4 detector was saturated by thermal emission from the warming telescope. The sensitivity achieved in the W1 and W2 bands was similar to that during the full cryogenic mission phase. The W3 measurement sensitivity was degraded and decreased steadily during the 3-Band Cryo phase because of the increasing telescope temperature and decreasing exposure times. The WISE 3-Band Cryo Image Atlas is comprised of 5,649 4095x4095 pix at 1.375"/pix FITS format image sets. Each image set consists of intensity images, coverage maps, and uncertainty maps, one each for the W1, W2, and W3 bands.

- Description:
- NASA's Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010) mapped the sky at 3.4, 4.6, 12, and 22 um (W1, W2, W3, W4) in 2010 with an angular resolution of 6.1", 6.4", 6.5", & 12.0" in the four bands. During the full cryogenic survey phase, 7 January 2010 to 6 August 2010, when the detectors and telescope were cooled by solid hydrogen in both inner and outer cryogen tanks, WISE achieved 5 sigma point source sensitivities better than 0.08, 0.11, 1 and 6 mJy in unconfused regions on the ecliptic in the four bands. The sky was covered 1.2 times during this period, and the data acquired were used to construct the products for the March 2012 WISE All-Sky Data Release. The WISE 3-Band Cryo survey phase began on 6 August 2010 following the exhaustion of frozen hydrogen in the payload's outer cryogen tank. WISE scanned approximately 30% of the sky over the next 54 days while the focal planes were cooled by hydrogen ice in the inner cryogen tank. The telescope warmed from the 12 K maintained during the main mission to 45 K. Imaging data in the 3.4, 4.6 and 12 um bands were acquired, but elevated thermal emission from the telescope prevented useful data from being collected in the 22 um band. As illustrated in Figures 1 and 2, the 3-Band Cryo 3.4 and 4.6 um band measurements are nearly as sensitive as those in the full cryogenic survey, but the increasing temperature and reduced exposure times of the 12 um measurements result in significantly lower sensitivity.

- Description:
- From the <a href="https://wise2.ipac.caltech.edu/docs/release/allsky">WISE mission site:</a>. <hr> NASA's Wide-field Infrared Survey Explorer (WISE) mapped the sky at 3.4, 4.6, 12 and 22 micrometers in 2010 with an angular resolution of 6.1", 6.4", 6.5" and 12.0" in the four bands. WISE achieved a 5 sigma point source sensitivities better and 0.08, 0.11 1 and 6 mJy in unconfused regions on the ecliptic in the four bands. Sensitivity improves toward the ecliptic poles due to denser coverage and lower zodaical background. <p> The WISE All-WISE includes all data taking during the WISE full cryogenic phase, from January 7, 2010 to August 6, 2010, that were processed with improved calibrations and reduction algorithms and combines this with the NEOWISE postcryogenic survey to form the most comprehensive view of the full mid-infrared sky. bibcode=1995ApJ...451..564V,2010ApJ...713..912W <hr> <p> SkyView includes the four WISE bands as separate surveys. Many non-image data products are available at the WISE site. Note that WISE data is distributed in relatively large (>50 MB) image files. When SkyView generates an image for a part of the sky where it has not yet cached the data from the IPAC server there may be a delay as full tiles are downloaded even when only a small fraction of a tile is needed. Images in cached regions, are generated much faster. Access to the WISE data uses the VO SIA interface maintained at IPAC. Even when data is cached, the SIA service must still be available for successful queries. Provenance: WISE Archive (IRSA/IPAC). This is a service of NASA HEASARC.

- Description:
- These survey represents a combination of the 9-year data combined in a way that is intended to minimize the contribution from the galaxy. The data measure the temperature deviation from a uniform black body. <p> The original data are available at the <https://lambda.gsfc.nasa.gov>LAMBDA archive</a>. <p> The original data are stored in HEALPix pixels. SkyView treats HEALPix as a standard projection but assumes that the HEALPix data is in a projection plane with a rotation of -45 degrees. The rotation transforms the HEALPix pixels from diamonds to squares so that the boundaries of the pixels are treated properly. The special HealPixImage class is used so that SkyView can use the HEALPix FITS files directly. The HealPixImage simulates a rectangular image but translates the pixels from that image to the nested HEALPix structure that is used by the WMAP data. </p> Provenance: WMAP Mission/LAMBDA archive.

- Description:
- This is the XMM-Newton Master Catalog and Public Archive table which has been created from information supplied to the HEASARC by the XMM-Newton Project. It is periodically updated as necessary. This database table contains the list of observations which have already been made by the XMM-Newton observatory, as well as those which are scheduled to be made in the near future (usually a a few weeks to a month ahead of the present). It does not contain observations which are scheduled to be performed further in the future, nor does it contain accepted observations which have not yet been scheduled. The list of all accepted XMM-Newton observations, including a number of ones which are unlikely to ever be carried out, such as accepted priority C targets, is available in the XMMAO Browse table. This table includes entries for both pointed data and for data obtained during spacecraft slews. The slew observations all have obsid values beginning with the digit 9 and, because they were not made at a fixed position, lack any positional information such as RA and Declination. Some XMM-Newton observations for which the archived data has become publicly available as indicated by the public_date parameter value, i.e., the proprietary period has expired, are not currently available at the HEASARC: such cases will have values of 'N' for the data_in_heasarc parameter. These datasets in most cases are available at the ESA XMM-Newton Science Archive (XSA) at <a href="http://nxsa.esac.esa.int/nxsa-web/">http://nxsa.esac.esa.int/nxsa-web/</a>. For much more detailed information on the XMM-Newton instruments and their operation, please refer to the XMM-Newton Users Handbook at <a href="http://heasarc.gsfc.nasa.gov/docs/xmm/uhb/">http://heasarc.gsfc.nasa.gov/docs/xmm/uhb/</a>. This database table was created by the HEASARC based on information supplied by the XMM-Newton Project at the following URLs: <pre> <a href="http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaobslog.txt">http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaobslog.txt</a> <a href="http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaslewlog.txt">http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaslewlog.txt</a> <a href="https://xmm-tools.cosmos.esa.int/external/xmm_mission_plan/odf_pps/catstrip.shtml">https://xmm-tools.cosmos.esa.int/external/xmm_mission_plan/odf_pps/catstrip.shtml</a> </pre> It is periodically updated within a few days of whenever these XMM-Newton Project's URLs are modified.

- Description:
- The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
