Abstract. We present the analysis of Hα spectra obtained during a two-ribbon flare observed on the solar disk on May 16, 1981 at Yunnan Observatory with the Spectra-Spectroheliograph (SSHG). The complicated asymmetric profiles produced by the post-flare loops overlying flare ribbons are analysed with a fast method based on the cloud model method. This method takes into account the bright background of the loops and allows computation of the physical quantities of loops crossed by the slit: velocity field, optical thickness, source function and Doppler width. Using the scanning spectra of the region, we obtain 2-D maps of these parameters. The validity of the method used is compared with other methods and the sensitivity of parameters to solution is discussed in details. The results obtained with this method are compared with those given by Heinzel et al. (1992) using a fully non-LTE approach. Key words: Sun: flares – methods: data analysis 1.

Spectral analysis is a statistical approach for analysing stationary time series data in which the series is decomposed into cyclical or periodic components indexed by the frequency of repetition. Spectral analysis falls within the frequency domain approach to time series analysis. The spectral density function plays the central role and it summarizes the contributions of cyclical components to the variation of a stationary time series. The spectral density at frequency zero is particularly important because of its direct link to the variance of a time series sample average, that is, the long-run variance.
