Notes. Only those parameters that are varied in this work are listed. Values from the DV21 reference model are underlined. For the rest of the parameters, not listed here, we selected the values of the reference model as presented in DV21 (see their Sect. 6). ( † ) See Eq. (4). ( ★ ) THEMIS model parameters; see Eq. (11) of DV21.
