Maps from MIRI-MRS of various atoms and ions toward the Class 0 protostar Serpens SMM3. The white contours in the top-left panel outline the dust disk seen in millimeter continuum. Beam sizes are indicated in the lower left corner of each panel. Each panel is scaled to the maximum emission of that species. The maximum and minimum colors are (in Jy km s^-1), from top left to bottom right: [Fe II] 5.34 (0.033, 0.003); [Fe II] 17.94 (0.84, 0.017); [Fe II] 24.52 (0.62, 0.025); [Fe II] 25.99 (1.86, 0.075); [Ni II] 6.64 (0.05, 0.002); [Ni II] 10.68 (0.006, 0.001); [Ni II] 12.73 (0.005, 0.001); [Ne II] 12.81 (0.017, 0.003); [S I] 25.25 (3.27, 0.033).
