Left: ROSAT PSPC ﹩\frac{1}{4}﹩ keV intensity distribution superposed as contours on the H I 21 cm map of Ho II. The numbers denote the X‐ray sources according to Table 2. The arrows point to the center of each X‐ray source. The contour lines start at the 3 σ level, in incremental steps of 1 σ (angular resolution smoothed to 75﹩\arcsec﹩). Right: ROSAT PSPC total (0.1 keV to 2.1 keV) X‐ray intensity distribution superposed as contours on the H I 21 cm map of Ho II. The contour lines start at the 3 σ level incrementing in steps of 2 σ. Note that the individual sources 2, 3, 4, and 12 are not positionally coincident with ﹩\frac{1}{4}﹩ keV X‐ray sources and thus may be unrelated background sources (see discussion in the text).
