Integrated intensity maps (i.e., moment 0 maps) of 12 emission lines of eight O-COMs in NGC 1333 IRAS 2A. The quantum numbers, E_up, A_ij of each transition are labeled in white text. The contours in light purple indicate the continuum emission at the 30, 50, 100, 200, 300, 400, and 500σ levels (σ = 0.2 mJy beam⁻¹). The beam size (0.1″ × 0.15″) is denoted by white ellipses in the lower right, and the pixel where the spectrum was extracted is marked by a green cross in each panel. The beam size in the fifth panel is slightly smaller (0.08″ × 0.11″), since this transition lies in a different spectral window than the others.
