Cross sections of the nitrogen atom in \AA$^2$ for the direct
ionization, excitation-autoionization, total ionization from the ground
level $2s^22p^3\ ^4$S and metastable $^2$D and $^2$P terms, and the cross
section for the ground (70\%)--metastable (30\% $^2$D) mixture as
functions of the incident electron energy $T$ in eV.}
