cds-question@unistra.frgalaxiesx-ray-sourcesx-ray-binary-starsWe present comprehensive X-ray point source catalogs of NGC55, NGC2403, and NGC4214 as part of the Chandra Local Volume Survey. The combined archival observations have effective exposure times of 56.5ks, 190ks, and 79ks for NGC55, NGC2403, and NGC4214, respectively. When combined with our published catalogs for NGC300 and NGC404, our survey contains 629 X-ray sources total down to a limiting unabsorbed luminosity of ~5x10^35^erg/s in the 0.35-8keV band in each of the five galaxies. We present X-ray hardness ratios, spectral analysis, radial source distributions, and an analysis of the temporal variability for the X-ray sources detected at high significance. To constrain the nature of each X-ray source, we carried out cross-correlations with multi-wavelength data sets. We searched overlapping Hubble Space Telescope observations for optical counterparts to our X-ray detections to provide preliminary classifications for each X-ray source as a likely X-ray binary, background active galactic nucleus, supernova remnant, or foreground star.2015AJ....150...94Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/94CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)B/hst : HST Archived Exposures Catalog (STScI, 2007)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/ApJ/763/128 : Chandra Local Volume Survey: NGC 404 sources (Binder+, 2013)J/ApJ/758/15 : Chandra X-ray point sources of NGC 300 (Binder+, 2012)J/ApJS/193/31 : M33 Chandra ACIS survey: final catalog (Tullmann+, 2011)J/AJ/133/917 : HST photometry of two NGC 4214 clusters (Ubeda+, 2007)J/MNRAS/370/25 : XMM observations of NGC 55 (Stobbart+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/94https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/94http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/94https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/94https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/94http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/94GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/150/94/galaxies (Galaxies from Chandra Local Volume Survey (CLVS))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/94/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/94/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/94/galaxies?GETtext/xml+votable180.050000true3.723333-39.1966670.005555555555555556Cone search capability for table J/AJ/150/94/table5 (Expanded X-ray source lists for all galaxies in the Chandra Local Volume Survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/94/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/94/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/94/table5?GETtext/xml+votable180.050000true13.5499167-37.66438890.0055555555555555566/2282 7741 7743 7784 7786 28630 28631 35512 35514 35536 355388.650015785639275e-20 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/94?format=asciiX-raydefaultJ/AJ/150/94/sourcesHardness ratios (table 8) , and classification (table 20) of X-ray sourcesrecnoRecord number assigned by the VizieR team.
