Analysis of non-thermal velocities in the solar corona

We describe new ground-based spectroscopic observations made using a 40-cm aperture coronagraph over a whole range of radial distances (up to heights of 12' above the limb) and along four different heliocentric directions N, E, S and W. The analysis is limited to the study of the brightest...
