VizieR Online Data Catalog: The 3rd MSFRs Omnibus X-ray Catalog (MOXC3) (Townsley+, 2019)

The analysis methods for the Massive Star-forming Regions Omnibus X-ray Catalog, third installment (MOXC3) are nearly identical to those employed in MOXC2. The one major extension is that MOXC3 introduces the analysis of zeroth-order data from ACIS observations that included the Chandra High Energy Transmission Gratings (HETG; Canizares+ 2005PASP..117.1144C). MOXC3 also incorporates newly available Gaia DR2 (Gaia Collaboration, 2018, I/345) distances from the literature for most targets. Lastly, we revive our workflow for spectral fitting of diffuse X-ray emission regions from the Chandra Carina Complex Project (CCCP; Townsley+ 2011, J/ApJS/194/15 ; 2011ApJS..194...16T and 2011ApJS..194....1T) to ascertain the origins of prominent patches of diffuse X-ray emission in MOXC3 MSFRs. See Section 2 for further details.

Table 2 enumerates the 50 archival Chandra/ACIS observations used in MOXC3 by listing their unique Observation Identification (ObsID) numbers. Details are given in MOXC2 (Townsley+ 2018, J/ApJS/235/43). Most MOXC3 data were obtained with the ACIS Imaging Array (ACIS-I) configuration.
