Maps of the Hα emitting knots and corresponding KS relation in JO206, JO204, JO201, and JW100 from top to bottom, with different symbols for knots in the disk (circles) and in the tail (squares). Blue contours indicate knots dominated by the DIG. The size of each symbol is proportional to the size of the emitting region, and it is color-coded according to the S/N in the CO(2−1) line. The dashed red lines show lines of a constant depletion time (from 10⁸ to 10¹⁰ yr), while the dashed blue shows the relation at a 1 kpc scale from Bigiel et al. (2011). The dash-dotted black lines show the relation found analyzing independent beams, the slopes and intercepts of which are given in Table 3.
