Test-statistics map with 0°.01 pixel size in the 0.3–300 GeV energy band in the Kes 17 SNR field (see text for details). The blue contours delineating the SNR radio synchrotron emission are from the 843 MHz SUMSS map (levels 0.015, 0.15, and 0.30 Jy beam⁻¹, at the resolution of 45″). The positions and distances of the H II region G304.465–00.023 (Urquhart et al. 2022) and the two known pulsars, PSR J1306–6242 (Kramer et al. 2003) and PSR J1305–6256 (Manchester et al. 2001), lying in the field, are also labelled. The plus symbol and dark-green ellipse within the Kes 17 radio contours mark the best-fit position and 95% confidence region, respectively, for the GeV emission obtained with a point-source spatial template. The dashed brown circle traces the 95% confidence fitted size of the γ-ray source. The inset shows a ~15′ × 15′ close-up view of the Kes 17 region, centred at the position of the γ-ray excess.
