Diagnostics of chromospheric velocity fields
Abstract
This paper examines the possibility of recovering quantitative information on chromospheric velocity fields from high resolution (lambda/Delta lambda of about 100,000) spectrograms of the Ca II H and K resonance lines. A qualitative discussion of the observed features is given in terms of a schematic theory of line formation in the case of collisionally dominated resonance lines.
