Comparison of total Cl abundances obtained with and without ICF(Cl) for objects where Cl⁺ and/or Cl³⁺ abundances have been derived. Left and right panels show the results obtained when the Cl/H ratio is obtained using the ICF(Cl) by Amayo et al. (2021) or Izotov et al. (2006), respectively. Each data point is colour-coded by its ionisation degree and parameterised by the O²⁺/O ratio. The dotted line indicates the 1:1 relation. The red line in the left panel represents the linear fit to the data points. In the right panel, the dashed blue line represents the linear fit to all objects, and the solid red line represents the fit excluding objects with O²⁺/O > 0.9.
