Left: H₂ column density map (N_H2 in cm⁻²) of L694, computed from Herschel maps at 250,350, and 500 μm. The position of the continuum peak is represented by the blue cross. The red cross is at an off-position, used to show the different velocity profile in Fig. 2. Right: H₂ volume density (n_H2 in cm⁻³) obtained from the method presented in Marchal et al. (2019). In both maps, the temperature (in K) appears in white contours, and the spatial scale is represented by the horizontal white bar (10 000 AU).
