Integrated intensity of NH₃ (1,1) in Barnard 5. The black-solid and black-dashed contours show the two filaments and the three condensations in B5, respectively (contours and nomenclature adapted from Schmiedeke et al. 2021). The beam size and scale-bar are shown in the bottom-left and the top-right corners, respectively. The white-solid contour shows the core boundary calculated using single-dish observations by Pineda et al. (2010).
