Sample of maps belonging to the different families observed towards L1544. The full dataset is shown in Appendix A. The black dashed lines represent the 90%, 50%, and 30% of the H₂ column density peak value derived from Herschel maps (Spezzano et al. 2016b), 2.8 × 10²² cm^-2. The solid lines represent contours of the molecular integrated emission starting with 3σ with steps of 3σ (the rms of each map is reported in Table 1). The dust peak (Ward-Thompson et al. 1999) is indicated by the black triangle. The white circles represent the HPBW of the 30 m telescope.
