PACS spectral maps of the Class 0 source NGC 1333-IRAS4A in the CO 14–13, CO 24–23, [O i] 63.2 μm, H₂O 2₁₂–1₀₁, H₂O 2₂₁–1₁₀ and OH 84.6 μm lines. The center of each spaxel box corresponds to its position on the sky with respect to the pointed source coordinates from van Dishoeck et al. (2011); shown boxes are smaller than the actual spaxel sizes. Wavelengths in microns are translated to the velocity scale on the X-axis using laboratory wavelengths of the species and cover the range from –550 to 550 km s^-1, except for the OH 84.6 μm lines where –400 to 400 km s^-1 is shown. The Y-axis shows fluxes normalized to the brightest spaxel on the map separately for each species in a range –0.2 to 1.2. Outflow directions are drawn in blue and red lines based on CO 6–5 APEX CHAMP⁺ sub-mm maps (Yıldız et al. 2012, and in prep.) that traces the warm entrained gas (T ~ 100 K). Two red outflow (R_I, R_II), on-source (C) and blue outflow (B_I, B_II) spaxels are marked with letters. IRAS4A spectra at those positions in different species are shown in Appendix D. The contribution from NGC 1333-IRAS4B, located at (22.5″, –22.8″) with respect to IRAS4A, is seen in the S-E part of the map.
