One-dimensional spectroscopy of the solar photosphere

Data from a time series of spectrograms were used to study correlative relatio nships between intensity and velocity in the solar photosphere. The variations along the slit of the line parameters from two Fe lines lying in the visible range of the spectrum were used. The formation height difference of these line s is over 300 km. The temporal variations of the correlation coefficients were studied, they showed a strong influence of the 5 min-oscillations. A shorter period of the oscillations was found for the higher photosphere, whereas the a mplitude of the oscillations is there larger.
