Regions used for spectral extraction from Chandra data. The black ellipse called IXPE is the same as the source region in Fig. 2. The other three regions (SRC, Wings-n, and Wings-e) cover the compact source and the brighter parts of the X-ray bow. The SRC and Wings-n regions do not overlap. Larger regions (Wings-e and IXPE) include all the Chandra counts inside them; i.e., the IXPE region includes the counts from SRC, Wings-n, and almost the entire Wings-e counts. The purple circle labeled as IP shows the extraction region for the intermediate polar CXOUGC J174622.7−285218.
