Mutual space - time localization of the sector structure of the interplanetary magnetic field and the large - scale field of the Sun

On the basis of statistical comparison of the large-scale magnetic field of the Sun and the sector structure of the interplanetary magnetic field by different methods it is shown that regardless of their close interaction there can be slight discrepancies between them due to their inadequate determination and the presence of short-term disturbances. The border zone width between the beginning of the coronal hole and the boundary of the large-scale magnetic field of the Sun (about 40-50 heliographical degrees) is specified
