Notes.

(1)

The gas mass obtained as a fraction of the total mass of the galaxy from the CO position-velocity diagram;

(2)

the SFR obtained similarly from the [OII] position-velocity diagram, normalized with the total SFR determined according to Sect. 2.2;

(3)

the derived gas mass and SFR surface densities averaged over the same area of 1′′ in diameter;

(4)

the depletion time tdepl = Mgas/SFR; and

(5)

the FWHM obtained from the IRAM position-velocity diagram with a Gaussian fit in the direction of the slice (for information only). The FWHM roughly corresponds to the IRAM beam size, so we preferred to use the same 1′′ size for all clumps in the different calculations. Using the FWHM instead of a constant 1′′ diameter to calculate the surface densities gives a much larger scatter, but actually does not change the constant depletion time fit and the values of tdepl. The clumps are numbered from bottom to top according to the horizontal separation lines of Fig. 2.
