- Description:
- The NEOWISE Post-Cryo Preliminary Data Release contains 3.4 and 4.6 um (W1 and W2) Single-exposure image and extracted source data that were acquired by Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010) following the exhaustion of solid hydrogen in the satellite's payload inner and outer cryogen tanks. During this period, known as the NEOWISE Post-Cryo survey phase, the WISE optics and focal plane assemblies warmed to 73.5 K, and the W1 and W2 HgCdTe detectors continued to operate with sensitivities close to those achieved during the full cryogenic mission phase. No useful data were obtained by WISE's 12 and 22 um Si:As detectors because of the higher temperatures. WISE scanned approximately 70% of the sky during the Post-Cryo phase, completing a survey of the inner Main Asteroid Belt, and a second coverage epoch of the inertial sky.

- Description:
- The Near-Earth Object Wide-field Infrared Survey Explorer Reactivation Mission (NEOWISE; Mainzer et al. 2014, ApJ, 792, 30) is a NASA Planetary Science Division space-based survey to detect, track and characterize asteroids and comets, and to learn more about the population of near-Earth objects that could pose an impact hazard to the Earth. NEOWISE systematically images the sky at 3.4 and 4.6 μm, obtaining multiple independent observations on each location that enable detection of previously known and new solar system small bodies by virtue of the their motion. Because it is an infrared survey, NEOWISE detects asteroid thermal emission and is equally sensitive to high and low albedo objects. The NEOWISE 2015 Data Release is the first annual release of Single-exposure data, and contains all observations from the first year of survey operations, 13 December 2013 to 13 December 2014 UTC. NEOWISE scanned the sky nearly two complete times during this period, accumulating 24 or more independent exposures on each point on the sky. The 2015 NEOWISE Release data products include single-exposure Images - 2,497,867 calibrated 1016x1016 pix @2.75"/pix FITS image sets for the individual 7.7 sec W1 and W2 NEOWISE survey exposures. Each image set consists of two intensity images, noise maps, and bit-masks indicating pixel use status, one each for the W1 and W2 bands.

- Nine Year INTEGRAL IBIS 17\-35 keV Galactic Plane Survey: Exposure
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This survey combines 9 years of INTEGRAL IBIS observations from December 2002 through January 2011 into a single Galactic Plane image. A total of 135 megaseconds of exposure is included in the observations used. Survey data is generated for the Galactic plane in the region |b| <= 17.5. The original flux data has been convolved with 5' seeing kernel. To minimize loss of resolution in transformations, the Lanczos sampler is suggested as the default, but may be overriden by the user. Both the preconvolved and standard convolved maps are available at the <a href="https://web.archive.org/web/20170620112312/https://hea.iki.rssi.ru/integral/nine-years-galactic-survey/index.php">Website</a>. <p> The exposure and sensitivity vary considerably over the coverage region, but 90% of the field has a limiting sensitivity better than 2.2 x 10<sup>-11</sup>ergs s<sup>-1</sup>cm<sup>-2</sup> or about 1.56 mCrab. Further details of the survey construction are given in the reference. <p> The flux and significance maps use the PSF convolved maps from the survey. The flux maps are in millicrab units. Exposure maps (with exposures in seconds) were from the exposure extension in the MAPDLD files and give the dead-time corrected exposure in seconds. <p> Links to the exposure and significance maps corresponding to the requested region will be given in the Web output. These maps can be generated directly in the CLI interface. For each waveband the flux, significance and exposure maps are available with just the end of the survey names distinguishing them (e.g., INT Gal 17-35 [Flux|Sig|Exp] or INTGal1735[F|S|E]) Provenance: <a href="https://adsabs.harvard.edu/cgi-bin/bib_query?arXiv:1205.3941">Krivonos et al., 2012</a><br> Based on observations with INTEGRAL, an ESA project with instruments and science data centre funded by ESA member states (especially the PI countries: Denmark, France, Germany, Italy, Switzerland and Spain), Poland, and participation of Russia and the USA..

- Description:
- <i> SkyView </i> has copied the NVSS intensity data from the NRAO FTP site. The full NVSS survey data includes information on other Stokes parameters. <p> Observations for the 1.4 GHz NRAO VLA Sky Survey (NVSS) began in 1993 September and should cover the sky north of -40 deg declination (82% of the celestial sphere) before the end of 1996. The principal data products are: <ol> <li> A set of 2326 continuum map "cubes," each covering 4 deg X 4 deg with three planes containing Stokes I, Q, and U images. These maps were made with a relatively large restoring beam (45 arcsec FWHM) to yield the high surface-brightness sensitivity needed for completeness and photometric accuracy. Their rms brightness fluctuations are about 0.45 mJy/beam = 0.14 K (Stokes I) and 0.29 mJy/beam = 0.09 K (Stokes Q and U). The rms uncertainties in right ascension and declination vary from 0.3 arcsec for strong (S > 30 mJy) point sources to 5 arcsec for the faintest (S = 2.5 mJy) detectable sources. <li> Lists of discrete sources. </ol> The NVSS is being made as a service to the astronomical community, and the data products are being released as soon as they are produced and verified. <P> The NVSS survey is included on the <b>SkyView High Resolution Radio Coverage </b><a href="https://skyview.gsfc.nasa.gov/images/high_res_radio.jpg"> map</a>. This map shows coverage on an Aitoff projection of the sky in equatorial coordinates. <p> Provenance: National Radio Astronomy Observatory. The NVSS project includes J. J. Condon, W. D. Cotton, E. W.

- Description:
- The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 2012 June 13, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3 to 79 keV, extending the sensitivity of focusing instruments far beyond the ~10 keV high-energy cutoff achieved by all previous X-ray satellites. The inherently low background associated with concentrating the X-ray light enables NuSTAR to probe the hard X-ray sky with a more than 100-fold improvement in sensitivity over the collimated or coded mask instruments that have operated in this bandpass. The observatory was placed into a 600-km altitude, 6 degree inclination circular orbit, and consists of two co-aligned grazing-incidence X-ray telescopes pointed at celestial targets by a three-axis stabilized spacecraft. NuSTAR has completed its two-year primary science mission, and, with an expected orbit lifetime of more than 10 years, the opportunity for proposing observations as part of the General Observer (GO) program is now available, with observations beginning in 2015. Using its unprecedented combination of sensitivity and spatial and spectral resolution, NuSTAR offers opportunities for a broad range of science investigations, ranging from probing cosmic ray origins to studying the extreme physics around compact objects to mapping micro-flares on the surface of the Sun. NuSTAR also responds to targets of opportunity including supernovae and gamma-ray bursts. This table contains a list of (a) unobserved targets that are planned or have been accepted for observation by NuSTAR in the future and (b) NuSTAR observations which have been processed and successfully validated by the NuSTAR Science Operation Center. 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. Entries with the status field set to 'accepted' are targets approved for scheduling, and the planned exposure time given in the exposure_a (and exposure_b) parameter will have a negative value for those targets. This database table is based on information supplied by the NuSTAR Project at Caltech. It is automatically updated on a regular basis. This is a service provided by NASA HEASARC .
