Abstract

Two sets of spectra selected by their prominent coronal line emission were analyzed with the purpose of characterizing the kinematics of clouds emitting coronal lines. Values of full width at the half the maximum (FWHM), shift of the peak emission (∆v), kurtosis and asymmetry both of coronal lines and some low ionization lines (these latter for comparison) are presented. For the majority of the objects no correlation between ionization potential and FWHM it is observed, particularly if [Fe x] λ6374 and [Fe xi] λ7892 lines are include Regarding thes hiftingof the peake mission most of the objects show blue shift where as just 15% showed as lightred shift oronal lines. There weak correlations between FWHM and v for coronal lines (FWHM), Finally,there is some indication tha the radio luminosity has influence in the shiftof the peak emission of coronal lines suggesting that jet radiois intervening ity of the of the outflows of these lines.
