Dependency on Redshift. Top panel: DM_host as a function of redshift. Black and red points correspond to DM${}_{\mathrm{host}}^{\mathrm{direct}}$ and DM${}_{\mathrm{host}}^{\mathrm{Macquart}}$, respectively. The black line is the tendency of DM${}_{\mathrm{host}}^{\mathrm{direct}}$. Negative values for DM${}_{\mathrm{host}}^{\mathrm{Macquart}}$ are nonphysical; we nevertheless report them for statistical consistency. A histogram of the different samples is shown to the right following the same color scheme. Bottom panel: Difference between DM${}_{\mathrm{host}}^{\mathrm{direct}}$ and DM${}_{\mathrm{host}}^{\mathrm{Macquart}}$ as a function of redshift (purple dots). The dashed black line at value 0 indicates where DM${}_{\mathrm{host}}^{\mathrm{direct}}$ and DM${}_{\mathrm{host}}^{\mathrm{Macquart}}$ are equal. A histogram of the sample is shown in the right panel.
