Comparison of the spatially-resolved total gas Schmidt relation for nine spiral galaxies in this work with the global Kennicutt–Schmidt relation of the starbursts (black stars) and spirals (yellow dots) taken from Kennicutt (1998b), low surface brightness galaxies (LSBs, orange triangles) from Wyder et al. (2009) and dwarf irregular galaxies (dIrrs, pink squares) from Roychowdhury et al. (2017). The diffuse background has been subtracted from the SFR tracers as well as from the atomic gas for the spatially-resolved data (blue dots with green error bars). These local measurements assume a Salpeter IMF and an X(CO) factor of 2.8 × 10²⁰ cm⁻² (K km s⁻¹)⁻¹ to match the parameters adopted in Kennicutt (1998b). The pink line represents the global Kennicutt–Schmidt relation from Kennicutt (1998b) while the solid black line is the best-fit line to the spatially-resolved data from all galaxies in this work.
