Field of view for the Chandra ACIS observation of SNR DA 530 compared with its outer boundary, as outlined by a single 1420 MHz continuum intensity contour at 2 mJy beam⁻¹ (L99). Detected pointlike sources (Fig. 3) have been excluded. The regions are used to extract spectra (see § 3). "S" marks the extraction region for the extended hard X‐ray feature.
