Extreme limb observations of Ba II λ 4554 and Mg i λ 4571
Abstract
Profiles of the Ba II λ 4554 resonance line and the Mg I λ 4571 intercombination line are presented, observed near the limb of the Sun. They are obtained from eclipse spectrograms with good spectroscopic resolution and an accurate height calibration. The reduction of the observations is described and detailed profiles are given for a range of viewing angles (1/cos θ = 4 - 22).
