Key Takeaway Key Takeaway: The emergent line radiation contribution function and line depresssion contribution function provide similar results for Zeeman split spectral lines, with some cases where one function is more suitable than the other.
Abstract
The recently introduced emergent line radiation contribution function (Achmad et al. 1991; Gurtovenko et al. 1991) is extended to the Stokes vector of Zeeman split spectral lines. This contribution function is compared to the line depresssion contribution function on the basis of an analytical relation and of numerical NLTE computations of a set of spectral lines. In general the two contribution functions give very similar results, although in some cases the one or the other of them is more suitable
