Table 1 \(T-A\), \(\sqrt{\sigma _T \sigma _A}\), T / A separation, and success rate

Difference (\(T - A\)) between average \(\xi ^\mathrm{GEO}_z\)s in toward (T) and away (A) IMF sectors, geometric mean (\(\sqrt{\sigma _{T}\sigma _{A}}\)) of the standard errors of \(\xi ^\mathrm{GEO}_z\)s in T and A sectors, “T / A separation” (\(= (T - A)/\sqrt{\sigma _{T}\sigma _{A}}\)) and “success rate” (see text) derived from Nagoya GG-component, GMDN, and NM (Thule–McMurdo) data in 2006–2013 on daily and hourly bases
