Continuum-subtracted PACS map of the integrated H₂O 2₁₂–1₀₁ emission along the L1448 outflow. Sources in the region are indicated with crosses: L1448-C(S) and C(N) in the central region, and L1448 NA, NB, and NW in the northern region. The diffraction-limited beam of FWHM 12.6″ is also indicated. The different emission peaks are labeled following the nomenclature adopted by Bachiller et al. (1990) for individual CO peaks. The average rms noise in the observed region is of about 2 × 10^-6 erg s^-1 cm^-2 sr^-1. Contours are drawn at 3σ, 6σ, 9σ, 12σ, 16σ, 30σ, 50σ, and 75σ. Negative contours are indicated by dashed lines.
