1.39 mm continuum emission, toward region F2 (left panel) and region F3 (right panel), in contours that depict [10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 300, 500, and 700] times the rms noise (0.12 mJy beam⁻¹), overlapped with magnetic field segments in blue, where thin and thick segments depict segments within the inner 50% and 40% of the primary beam model, respectively. At 350 μm, the red segments show the CSO magnetic field. The thin segments have a polarization intensity between two and three sigmas, and the thick segments have an intensity greater than three times sigma (CSO sigma =0.02 Jybeam⁻¹ Añez-López et al. 2020). Color contours show leaves from dendrogram analysis, also black label present the corresponding ID label. Blue solid circle depict the ALMA beam size. The Pink triangle shows the H₂ O maser detected in Wang et al. (2006). Yellow tripods depict radio sources detected at 6 cm (C-band) by Díaz-Márquez et al. (2024). White tripods show NH₃ cores detected by Ohashi et al. (2016).
