✦ Synopsis

The Goldberg-Unno method is analysed. Accounting for the instrumental profile correction reduces the derived microturbulent velocities only slightly. A similar effect may be caused by an unresolved macroturbulence. The method of accounting for the damping effect is considered. The correction for the influence of the damping effect does not change substantially the general trend of the variation of ~ with ~0. The microturbulent velocity ~t is reduced appreciably.

An attempt to analyse the microturbulent velocities by the Goldberg-Unno method under deviation from LTE is made.

The main conclusion is that the Goldberg-Unno method, especially in its modified form, is valid and useful.
