Abstract

The absolute limb effect is presented for Fei lines λ 3767 and λ3969; for five Tii lines of multiplet 42 near λ 4535 and one Tiii line at λ 4534; two lines of Mgi, λ 4571 and λ 5172; two lines of Baii at λ 5854 and λ 6497. The scattered light of the McMath solar telescope is illustrated by several figures but not applied to the limb-effect observations. It is suggested that the supergravity shift at the limb is the result of scattering of the atoms in anisotropic velocity field.
