Note to the table: The different ISM phases are molecular 
medium (MM), cold neutral medium (CNM), warm neutral medium (WNM), warm 
ionized medium (WIM) and hot ionized medium (HIM). $T$ is the 
temperature, $B$ the magnetic field strength, $n_{\rm H}$ the 
hydrogen density, $f_{\rm ion} = n_{\rm i} / (n_{\rm i} + n_{\rm n})$ 
the ionization fraction, $n_{\rm i}$ the ion density, $k_{\pa{\rm 
max}}$ the maximum parallel wavenumber of Alfv\'en waves (right-hand 
side of Eq.~(\ref{Eq:thr_kpar_bis})), and $E_{\rm k,min}$ the minimum 
kinetic energy required for positrons to interact resonantly with 
Alfv\'en waves (right-hand side of Eq.~(\ref{Eq:thr_KE_bis})). Here, 
we assume a pure-hydrogen gas, for which $n_{\rm i} = f_{\rm ion} ~ 
n_{\rm H}$ and $n_{\rm n} = (1 - f_{\rm ion}) ~ n_{\rm H}$. \vspace*{-2mm}
