Left: three-color image of HM1, made using the SAS “images” script. Red, green, blue correspond respectively to the soft, medium, and hard energy bands (see text for definition). The greenish source at the field’s center is WR89. Right: grayscale image of HM1, with the objects discussed in the text identified by their X-ray source number (see Table 1). In both images, orientation and scale are the same. The color version of this figure is available online.
