cds-question@unistra.frmolecular-cloudsmillimeter-astronomysubmillimeter-astronomyinterstellar-mediumWe present Orion A giant molecular cloud core catalogs, which are based on a 1.1mm map with an angular resolution of 36" (~0.07pc) and C^18^O (J=1-0) data with an angular resolution of 26.4" (~0.05pc). We have cataloged 619 dust cores in the 1.1mm map using the Clumpfind method. The ranges of the radius, mass, and density of these cores are estimated to be 0.01-0.20pc, 0.6-1.2x10^2^M_{sun}_ , and 0.3x10^4^-9.2x10^6^cm^-3^, respectively. We have identified 235 cores from the C^18^O data. The ranges of the radius, velocity width, LTE mass, and density are 0.13-0.34pc, 0.31-1.31km/s, 1.0-61.8M_{sun}_ , and (0.8-17.5)x10^3^cm^-3^, respectively. From the comparison of the spatial distributions between the dust and C^18^O cores, four types of spatial relations were revealed: (1) the peak positions of the dust and C^18^O cores agree with each other (32.4% of the C^18^O cores), (2) two or more C^18^O cores are distributed around the peak position of one dust core (10.8% of the C^18^O cores), (3) 56.8% of the C^18^O cores are not associated with any dust cores, and (4) 69.3% of the dust cores are not associated with any C^18^O cores.2015ApJS..217....7Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/217/7CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/244 : Atlas and Catalog of Dark Clouds (Dobashi+, 2005)J/A+A/564/A68 : Orion A GMC 13CO and C18O maps (Shimajiri+, 2014)J/AJ/144/192 : Spitzer survey of Orion A and B.
