      resonance for the first three modes~$m$ and with $n=1,2$, in the
      case of a Newtonian gravitational potential.  The results are
      given for a~$1.4~M_\odot$ neutron star rotating respectively
      at~$300$ and~$600$~Hz. The value on the left of the symbol/corresponds to the absolute value sign taken to be~$-$ and on the
