Example of cirrus confusion noise around the star HD 148387 (η Dra, OBSIDs1342186146, ..47, ..55, ..56 from OD 160). The left panel shows the HPF processed map used for the photometry, the photometric aperture with 10.′′ 7 radius is indicated by the red circle and a small white cross at its centre. The middle panel shows the Jscanam processed map which reproduces extended emission more reliably. The right panel shows the AKARI WIDE-L (140 μm) background emission around the source (red cross), the AKARI-map area is about four times as large as the PACS map area, which is indicated by the red dashed square.
