Combination of angle variables for different harmonics of Table 2 as a function of time along direct integrations 
of the Solar System presented in Laskar & Gastineau (2009) (n = 0 is the nominal solution). The angle variables correspond to the proper modes z•, ζ• defined in Laskar (1990a). The time series are low-pass-filtered with a cutoff frequency of (500 kyr)−1.
