Maps of the 179 μm line and continuum emission in the region around L1448-C sources, compared with CO(3–2) and H₂ lines at different excitation, namely the 0–0 S(0)(28 μm), 0–0 S(1)(17 μm), and 1–0 S(1)(2.12 μm). White contours, shown in the bottom right and upper left panels, for the line and continuum emission respectively, are drawn at the following values: 1.5, 2.0, 3.0, 4.0, 6.0 8.0  ×  10^-5 erg s^-1 cm^-2 sr^-1 for the line emission, and 0.6, 0.8, 1.2, 1.6 × 10^-3 erg s^-1 cm^-2 sr^-1 for the continuum emission.
