Abstract

Investigating the real origins of “error bars” prior to data processing can be highly rewarding. We have already shown it for solar radius determinations where uncertainties could be deduced from the dispersion of elementary measurements. In the present work, we extend our analysis to the historical monthly sunspot numbers where the “uncertainty” problem arises quite differently. This leads to a substantial revision of our initial method. Like in the radius case, we shall stress the interest of analysing procedures which have the capability of taking care of unequal error bars, such as the wavelet transform.
