Comparison between low-resolution and multi-resolution maps of dust temperature (upper) and H₂ column density (lower). The white and yellow polygons indicate the fields of view of the APEX and our ACA 7 m observations, respectively. For the temperature image, the resolution is ${18}_{\cdot }^{\mathrm{\prime }\mathrm{\prime }}2$ inside and ${36}_{\cdot }^{\mathrm{\prime }\mathrm{\prime }}3$ outside the white closed polygon. For the column density image, the resolution outside the yellow closed polygon is the same as the temperature map but as high as 6″ within the yellow closed polygon.
