  10. Effect of O+ on FLR frequency Hattingh, S. K. F. and P. R. Sutcliffe, Pc3 pulsation eigenperiod determination at low latitudes, J. Geophys. Res., 92, 12433, 1987. Fig. 3. The mean and standard deviation of the dominant pulsation periods of the H-component observed at the stations SAA (L=1.84), AUG (L=1.64), MAR (L=1.52) and TSU (L=1.37) are indicated by the circles and error bars, respectively. The short dashed line shows the periods computed using a plasma model containing both O+ and H+ as a function of L-value. The long dashed line shows the periods computed with the same H+ distribution, but with O+ excluded.
