Catalog of dense cores in the Orion A giant molecular cloud
  We present Orion A giant molecular cloud core catalogs, which are based on
1.1 mm map with an angular resolution of 36 arcsec (sim 0.07 pc) and C18O (1-0)
data with an angular resolution of 26.4 arcsec (sim 0.05 pc). We have cataloged
619 dust cores in the 1.1 mm map using the Clumpfind method. The ranges of the
radius, mass, and density of these cores are estimated to be 0.01 - 0.20 pc,
0.6 - 1.2 times 10^2 Msun, and 0.3 times 10^4 - 9.2 times 10^6 cm^{-3},
respectively. We have identified 235 cores from the C18O data. The ranges of
the radius, velocity width, LTE mass, and density are 0.13 -- 0.34 pc, 0.31 -
1.31 km s^{-1}, 1.0 - 61.8 Msun, and (0.8 - 17.5) times 10^3 cm^{-3},
respectively. From the comparison of the spatial distributions between the dust
and C18O cores, four types of spatial relations were revealed: (1) the peak
positions of the dust and C18O cores agree with each other (32.4% of the C18O
cores), (2) two or more C18O cores are distributed around the peak position of
one dust core (10.8% of the C18O cores), (3) 56.8% of the C18O cores are not
associated with any dust cores, and (4) 69.3% of the dust cores are not
associated with any C18O cores. The data sets and analysis are public.
