Notes. (1) Name of the FRB; (2) Stellar mass of host galaxy; (3) Halo mass of host galaxy (see Sect. 3.1.3); (4) DM of the halo of the host galaxy (see Sect. 3.1.3); (5) Empirical DM of the host galaxy (our main result; see Sect. 3.1.4); (6) Upper limit for the DM of the host galaxy (see Sect. 3.2); (7) Average DM of the host galaxy estimated from the Macquart relation (see Sect. 3.2).

†: Although negative values are nonphysical, we nevertheless report them as such for statistical consistency when taking the average of the ensemble.
