cds-question@unistra.frinterstellar-mediumspace-observatoriesobservational-astronomyinfrared-astronomyspectroscopyThis catalog contains the 278 low-resolution (R~20) near-infrared (1.8-5.3micron) spectra of diffuse sky covering a wide range of galactic and ecliptic latitudes with the Infrared Camera (IRC) on board AKARI before the exhaustion of liquid-helium (from September 2006 to May 2007). Advanced reduction methods specialized for the slit spectroscopy of diffuse sky spectra are developed for constructing this spectral catalog. Filter wheel of the IRC instrument has dark position to measure the dark current, and uncertainty due to dark current subtraction is estimated to be <3nW/m2/sr at 2micron (Tsumura & Wada, 2011PASJ...63..755T). Point sources brighter than mK(Vega)=19 were detected on the slit and masked for deriving the diffuse spectrum. It was confirmed that the brightness due to unresolved galactic stars under this detection limit is negligible (<0.5% of the sky brightness at 2.2 micron) by a Milky Way star count model (TRILEGAL; Girardi et al., 2005A&A...436..895G). Cumulative brightness contributed by unresolved galaxies can be estimated by the deep galaxy counts, being <4nW/m2/sr at K band in the case of limiting magnitude of mK=19 (Keenan et al., 2010ApJ...723...40K).2013PASJ...65..119Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/65/119CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/297 : AKARI/IRC mid-IR all-sky Survey (ISAS/JAXA, 2010)II/298 : AKARI/FIS all-sky survey PSC (ISAS/JAXA, 2010)II/327 : AKARI far-infrared surveyor YSO catalog (Toth+, 2014)J/A+A/537/A24 : AKARI NEP deep field mid-IR source catalogue (Takagi+, 2012)J/A+A/559/A132 : AKARI NEP deep survey revised catalog (Murata+, 2013)J/AJ/144/179 : AKARI-LMC point-source catalog (Kato+, 2012)J/AJ/145/32 : AKARI-LMC NIR spectroscopic catalog (Shimonishi+, 2013J/ApJ/784/53 : AKARI NIR spectral atlas of Galactic HII regions (Mori+ 2014)http://www.ir.isas.jaxa.jp/AKARI/Archive/Catalogues : AKARI Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/65/119https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/65/119http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/65/119https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/65/119https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/65/119http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/65/119GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/65/119/list (Source list for all spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/65/119/list?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/65/119/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/65/119/list?GETtext/xml+votable180.050000true90.038-66.6280.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/PASJ/65/119AKARI6/52 509 862 3245 3326 3668 4365 5284 5440 5630 5760 5835 5976 6015 6705 7308 7604 7777 7869 7973 8557 9388 9390 9770 10029 10031 10173 10239 11261 11482 11605 11607 11623 11636 11638 11833 12738 13205 13511 14666 14865 15278 15630 15683 15964 15967 16042 16078 16131 17264 17895 18753 18932 20155 20764 20958-20959 21327 21439 22555 22828 23226 23704 24287 24513 24516 25366 25526 26995 27289 27345 27495 28384 29098 30263 30268-30269 30623 31158 31172 32117 33015 33080 33091 33094 33097 33109 33115 33295 33317 33330 33563 33610 33955 34017 34262 34493 34723 34850 36489 37506 37546 37747 37791 37831 37834 37904 38048 38410 38531 38533 38912 40621 41797 41800 42777 43013 44998 45023 45107 46079 46130 46525 47509 48556 48614https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/65/119?format=asciiInfrareddefaultJ/PASJ/65/119/listSource list for all spectrarecnoRecord number assigned by the VizieR team.
