Eigenfunctions and energy density per logarithm pressure (measured in ergs) of the three lowest order modes with ﹩l=2﹩. The left panels display ﹩B=2\times 10^{12}\,\mathrm{G}\,﹩ and modes with redshifted frequencies of 27.4 (﹩n=0﹩; solid line), 521.5 (﹩n=1﹩; dashed line), and 637.2 Hz (﹩n=2﹩; dotted line). The right panels display ﹩B=10^{15}\,\mathrm{G}\,﹩ and modes with observed frequencies of 27.4 (﹩n=0﹩; solid line), 742.8 (﹩n=1﹩; dashed line), and 1329.2 Hz (﹩n=2﹩; dotted line).
