Abstract

Several formal solvers for polarised radiation are analysed for their numerical properties and for computational performance, in particular the Zeeman Feautrier (ZF) method of Auer et al. (1977) and the DELO method of Rees & Murphy (1987). It can be shown that in exchange for being at most 20% slower than DELO, ZF is robust, insensitive to the depth point distribution, substantially more accurate and particularly recommended for broadband polarisation calculations.
