Mean intensity enhancements in the PACS 100 (upper curve) and 160 μm (lower curve) images in sector 5 (see Fig. 4), zooming into the bowshock region discussed by Ladjal et al. (2010). When measured from the central target, the bowshock is clearly detected at 480′′ in the 160 μm image, and the corresponding feature is seen at 450′′ in the 100 μm image. The feature around 370′′ in the 100 μm image is not an “arc”, but more of a blob-like enhancement as can be seen in Fig. 4.
