Originální abstrakt

The special method of spectral analysis, based on statistical moments up to 4th order is presented. The method uses the sequence of digital images of chosen spectral absorption line as an input data obtained with the solar disc moving over the spectrograph slit. The mathematical analysis of these spectral sequences enables to cre- ate classical spectroheliograms, absorption in continuum, pure absorption in spectral line (without doppler and mag. field infuences), high quality dopplergrams and qualitative informations about magnetic field. The software called Helios-M implementing the de- scribed numerical methods was created. The possibility of this method we demonstrate on the dynamical effect, which was mesured in Ondrejov Observatory with the new post focus device | Solar Spectra Analyser.
