The CO(J=1-0) data set is from the second NANTEN CO survey (Fukui et al. 2008, Cat. J/ApJS/178/56) and the HI data set is from the merged Australia Telescope Compact Array (ATCA) and Parkes Telescope surveys (Kim et al. 2003ApJS..148..473K). File Summary:

Note (1): GMC name from Fukui et al. (2008, Cat. J/ApJS/178/56) (<[FKM2008] NNN> or <[FKM2008] LMC N JHHMM+DDMM> in Simbad). Note that in 68 cases, the name is truncated in JHHMM+DDM format. Note (2): These classes are interpreted as an evolutionary sequence from Type I to III; the lifetime of a GMC is estimated to be a few x10Myr in total. * Type I GMCs show no signs of active star formation in the sense that no O stars are being formed. * Type II GMCs are associated with small HII region(s), indicating the formation of isolated O stars, but do not host any stellar clusters identified by Bica et al. (1996ApJS..102...57B). * Type III GMCs are actively forming stars as shown by their association with large HII regions and young stellar clusters. Note (3): Position of peak integrated intensity. Data are from Fukui et al. (2008, Cat. J/ApJS/178/56). Note (4): HI cloud radius defined as R=(S/π)0.5. Here S is the cloud area, calculated by summing the areas of all pixels detected above 80% of the peak integrated intensity level. Note (5): HI clouds including two or more GMCs: the numbers show GMCs that are located in the same HI cloud.
