โœฆ Synopsis


In order to study the influence of the different treatment of the boundary conditions in different extrapolation schemes, the procedures of , Nakagawa and have been applied to the same (line-of-sight) magnetogram. The main field structure is similar for all three procedures, whereas in details there are clear differences, for example in the direction of the field lines in the overview, the heights to which the field lines extend, the number of field lines that leave the region, the field strength decrease with height, and the calculated amounts of magnetic energy in the chromospheric and coronal parts of the considered active region.
