Abstract:We offer to the star formation community the third installment of the Massive Star-forming Regions (MSFRs) Omnibus X-ray Catalog (MOXC3), a compilation of X-ray point sources detected in 50 archival Chandra Advanced CCD Imaging Spectrometer observations of 14 Galactic MSFRs and surrounding fields. The MOXC3 MSFRs are NGC2264, NGC6193, RCW108-IR, AurOB1, DR15, NGC6231, Berkeley87, NGC6357, AFGL4029, hPer (NGC869), NGC281, Onsala2S, G305, and RCW49 (Wd2); they have distances of 0.7-4.2kpc. Most exhibit clumped or clustered young stellar populations; several contain at least two distinct massive young stellar clusters. The total MOXC3 catalog includes 27923 X-ray point sources. We take great care to identify even the faintest X-ray point

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.
