Fig. 1.


Stokes images of spectral interval around Sr I 4607 Å line. The spatial direction spans ∼47″ on the solar disk. The observed regions were at different limb distances (μ = 0.2, 0.4, 0.5, 0.6, 0.7, and 0.8). The slit was placed parallel to the nearest limb. The reference direction for positive Stokes Q is the tangent to the nearest solar limb. These Stokes images are obtained after averaging over several frames (see Table 2). The granulation pattern is visible in the intensity Stoke image, especially in the continuum. The Q/I image shows the scattering polarization peak in the core of the Sr I line. Spatial variations at granular scales of this peak can be observed. The typical antisymmetric Zeeman patterns can be easily recognized in several Stokes V/I images.
