Descripción
The measurement of frequencies, linewidths, and splittings of low degree solar p-modes is a difficult task due, firstly, to time scales involved and, secondly, to the spurious presence of side lobes when data is not collected continuously. However, a long set of observations have been obtained at Observatorio del Teide: a total of 52 months of data, spread over 12 years (1977 to 1989), from which the best ones have been selected. These data allows averaging of power spectra, therefore giving statistical significant profiles for the p-modes, which can be fitted to appropriate functions (i.e. Lorentzian). Such analysis is applied to the data mentioned before and preliminary results of the aforementioned parameters are obtained.
