Fig. 5.


Scatter plot relating amplitudes of Sr I 4607 Å Q/I peak to normalized continuum intensity at different μ. The solid line represents a linear regression of the data. Its positive slope indicates larger polarization in the granulation. The Pearson correlation coefficient (r) value is annotated in each graph. The estimated error at all points is given by the error bar in the bottom left corner of each plot.
