Images of the three sources at 100   μm (top) and 160   μm (bottom) from Reduction 1 (Sect. 2). The images are displayed in a linear stretch from  −0.1   F_peak to F_peak of the source of interest. The peak flux is 0.38   mJy/pixel, 0.23   mJy/pixel, and 0.54   mJy/pixel at 100   μm and 0.17   mJy/pixel, 0.16   mJy/pixel, and 0.45   mJy/pixel at 160   μm for HIP 103389, HIP 107350, and HIP 114948, respectively. The white circles in the 160   μm images are centered on the brightest pixel of the source, respectively.
