Figure for cores 1-7 showing evolutionary stage classification (prestellar: green; protostellar: orange) based on outflow and warm gas tracers. Left column displays 1.3 mm continuum (grayscale with black contours at 1.3 × 10⁻⁴ Jy beam⁻¹ km s⁻¹ ×(5, 10, 20, 40, 80, 160) overlaid with CO (2-1) outflow maps (blue/red contours at 0.045 Jy^° beam km s⁻¹ ×(5, 10, 20, 40, 80, 160), integrated over 5 to 15 kms from systemic velocity; arrows indicate flow direction). Columns 2-5 show integrated intensity maps of molecular line tracers (5 km s⁻¹ integration width) with contour levels σ_line ×(5, 10, 20, 40, 80). In all panels the core is indicated by one ellipse, with green color indicating prestellar, orange indicating protostellar.
