Fig. 18


Centre-to-limb variation of the Fe i line at 617.3 nm. Top panels: variation of equivalent width (right) and FWHM (left) of the line as functions of μ. Bottom panels: convective Doppler shift (translated into line-of-sight velocity) of the line wings (right; 5% level of max. line depth) and the line core (left) as functions of μ (positive = redshift). The gravitational redshift is neglected.

This figure is made of several images, please see below:
