cds-question@unistra.fractive-galactic-nucleinorth-galactic-poleseyfert-galaxiesx-ray-sourcesWe present data products from the 300ks Chandra survey in the AKARI North Ecliptic Pole (NEP) deep field. This field has a unique set of 9-band infrared photometry covering 2-24 micron from the AKARI Infrared Camera, including mid-infrared (MIR) bands not covered by Spitzer. The survey is one of the deepest ever achieved at ~15 micron, and is by far the widest among those with similar depths in the MIR. This makes this field unique for the MIR-selection of AGN at z~1. We design a source detection procedure, which performs joint Maximum Likelihood PSF fits on all of our 15 mosaicked Chandra pointings covering an area of 0.34 square degree. The procedure has been highly optimized and tested by simulations. We provide a point source catalog with photometry and Bayesian-based 90 per cent confidence upper limits in the 0.5-7, 0.5-2, 2-7, 2-4, and 4-7keV bands. The catalog contains 457 X-ray sources and the spurious fraction is estimated to be ~1.7 per cent. Sensitivity and 90 per cent confidence upper flux limits maps in all bands are provided as well. We search for optical MIR counterparts in the central 0.25 square degree, where deep Subaru Suprime-Cam multiband images exist. Among the 377 X-ray sources detected there, ~80 per cent have optical counterparts and ~60 per cent also have AKARI mid-IR counterparts. We cross-match our X-ray sources with MIR-selected AGN from Hanami et al. Around 30 per cent of all AGN that have MID-IR SEDs purely explainable by AGN activity are strong Compton-thick AGN candidates.2015MNRAS.446..911Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/446/911CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)J/PASJ/59/S529 : NEP deep survey at 11um (Lee+, 2007)J/A+A/517/A54 : 20cm survey of the AKARI NEP (White+, 2010)J/ApJS/190/166 : Optical catalog of AKARI NEP-wide survey (Jeon+, 2010)J/A+A/537/A24 : AKARI NEP-Deep field mid-IR source catalogue (Takagi+, 2012)J/A+A/548/A29 : IR source catalog of AKARI NEP-Wide field (Kim+, 2012)J/A+A/559/A132 : AKARI NEP Deep Survey revised catalog (Murata+, 2013)J/ApJS/207/37 : IR sources spectroscopy in the AKARI NEP (Shim+, 2013)J/A+A/566/A60 : Optical-NIR catalog of AKARI NEP Deep Field (Oi+, 2014)J/ApJS/214/20 : AKARI NEP field J- and H- band source catalog (Jeon+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/446/911https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/446/911http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/446/911https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/446/911https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/446/911http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/446/911GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/446/911/mainscat (Main source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/911/mainscat?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/911/mainscat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/911/mainscat?GETtext/xml+votable180.050000true268.8226966.540620.005555555555555556Cone search capability for table J/MNRAS/446/911/lowpscat (Low probability source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/911/lowpscat?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/911/lowpscat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/911/lowpscat?GETtext/xml+votable180.050000true268.8226966.540620.005555555555555556Cone search capability for table J/MNRAS/446/911/list (List of FITS images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/911/list?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/911/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/911/list?GETtext/xml+votable180.050000true268.8826866.604210.0055555555555555566/11605 11607https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/446/911?format=asciiX-raydefaultJ/MNRAS/446/911/mainscatMain source catalogCID[1/626] Chandra source identification number within the catalog (CID)meta.idintprimaryNameName of object (4)meta.id;meta.maincharRAJ2000Right ascension (J2000.0) (RA)degpos.eq.ra;meta.mainDEJ2000Declination (J2000.0) (DEC)degpos.eq.dec;meta.mainePos[0.01/2.3] 1-{sigma} statistical error of source position (RADEC_ERR) (1)arcsecstat.errorfloatC0.5-7[1.7/7302] 0.5-7keV source counts (CTS_05_7)ctphot.count;em.X-rayfloate_C0.5-71-{sigma} uncertainty of C0.5-7 (CTS_ERR_05_7)ctstat.errorfloatR0.5-70.5-7keV vignetting-corrected source count rate (RATE_05_7)ct/ksphot.count;em.X-rayfloate_R0.5-71-{sigma} uncertainty of R05.-7 (RATE_ERR_05_7)ct/ksstat.errorfloatF0.5-7?=0 0.5-7keV source flux corrected for Galactic absorption);
