Comparison between two approaches to realization of the optimization method of nonlinear force-free field reconstruction
The main subject of investigation is comparative testing of two methods of nonlinear force-free field reconstruction within the bounded domain on the basis of optimization method. The first is the method with fixed boundary values and with using the weight function. The second one is the method with purposive varying of the boundary values. Both quantitative and qualitative characteristics are given which show the degree of conformity of calculated field and known model one. As shown, the second method of optimization gives the best approach to required one which corresponds to the finite solution in unbounded domain. This solution keeps its quality up to reconstruction domain boundaries.
