Abstract

In this Paper, we perform regressions on the solar observations made at the CERGA Observatory, through a moving window the size of which is chosen taking into account the physical constraints. After some statistical considerations, the results obtained with different sizes of window are analysed. Graphical comparisons are carried out on the estimators obtained by the usual method and by the new one for the 1978, 1979 and 1980 compaigns. They show that the latter is much more adequate to exhibit some periodic terms confirmed in the case of the sun demi-diameter through another analysis of oneothe authors (Laclare, 1985). Furthermore, the increased accuracy of the estimations in the parameters of the relative solar orbit (Bougeard and al 1983) shows that this method is relevant.
