[1.44] Toward Zeeman Magnetometry in the Corona: Line-of-Sight Effects

D. Rabin (NSO/NOAO)

One of the motivations for a large-aperture ground-based coronagraph is the possibility of measuring magnetic flux in the solar corona using the Zeeman sensitivity (Landé g = 1.5) of emission lines such as Fe XIV 530.3 nm, Fe X 637.4 nm, and Fe XIII 1074.7 nm. However, because the corona is optically thin, it is necessary to consider the effects of superposition along the line-of-sight on the interpretation of a detected Zeeman signal. Simple models are used to explore and illustrate the likely importance of line-of-sight confusion.
