Description
Summary:The results of research of halfwidhts ($\Delta\lambda$) and intensities (W) of Fe X $\lambda 6374 \AA$ and Fe XIV $\lambda 5303\AA$ spectral lines using observations obtained with the Large coronagraph of the Sayan observatory in 1968-1983 show the inverse correlation between $\Delta\lambda$ and W always exists for Fe X $\lambda 6374 \AA$; it takes place at all latitudes at the same height as well as with height irrespectively of activity level. For Fe XIV $\lambda 5303 \AA$ this correlation varies from direct to inverse depending on activity level. It is shown that relation type between $\Delta\lambda$ and W for different spectral lines is determined by different coronal structurednesses in these lines.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
