Spatial distribution of dense cores in I19074. The background shows ALMA 1.3 mm continuum emission. Blue dots mark core locations and the yellow solid line denotes the minimum path connecting these elements, given by the MST algorithm. The green dashed ellipses indicate clumps. The blue dashed contours are at [9, 15, 21, 27, and 33]× σ_{1.2 mm}. The synthetic beam of 0.60^′′ × 0.58^′′ for ALMA observations and the scale bar of 0.5 pc are shown in right corners.
