H and K lines in the sunspot umbra: A source function and Doppler width
Abstract
An inversion of line profiles H and K Ca II in the umbra of two sunspots is performed. By means of a numerical experiment, a tentative study of possible application of the method of intercomparison of lines in the multiplet (Goldberg's method) is made in cases when the condition of source function equality in multiplet is not fulfilled.
