  1. Difference (TA) between average \(\boldsymbol {\xi }^{\text {GEO}}_{\text {\textit {z}}}\) in toward (T) and away (A) IMF sectors, geometric mean (\(\sqrt {\sigma _{\text {\textit {T}}}\sigma _{\text {\textit {A}}}}\)) of the standard errors of \(\boldsymbol {\xi }^{\text {GEO}}_{\text {\textit {z}}}\)s in T and A sectors, ‘T/A separation’ (= (TA)/\(\sqrt {\sigma _{\text {\textit {T}}}\sigma _{\text {\textit {A}}}}\)), and ‘success rate’ (see text) derived from Nagoya, GMDN, and NM (Thule-McMurdo) data in 2006 to 2013 on daily and hourly bases.
