Maps from MIRI-MRS of the H2 S(1) line at 17.03 μm toward all JOYS sources. The top three rows show the low-mass protostars in order of increasing Tbol, whereas the bottom row shows the high-mass protostars. The white star(s) or arrow in each panel indicate the position of the protostar(s); for low-mass protostars those are derived from millimeter interferometry. A scale bar of 400 au is shown in each low-mass protostar panel, and a bar of 10 000 au in each high-mass protostar panel. The beam size is indicated in the lower left corner of the first panel. The maximum colors in each panel (in Jy km s-1) from the top left to bottom right for low mass are as follows: 0.59, 0.12, 0.03, 0.14, 0.08, 0.25, 0.08, 0.025, 0.041, 0.11, 0.006, 0.18, 0.31, 0.064. For high mass, they are 0.21, 0.02. 0.06, 0.021, 0.023, 0.027.
