EXCITATION OF CHROMOSPHERIC MG I,
Abstract
Our earlier analysis of chromospheric Mg I data is extended to discussions of both empirical and theoretical departures from radiative detailed balance in the strong singlet and triplet lines. At 500 km, general agreement between the empirical and theoretical values is obtained for all lines, assuming an isothermal, spherically symmetric atmosphere. At heights of 1000 and 1500 km, however, further evidence is found for strong departures from spherical symmetry. (Author)
