This tool allows to plot all variables of the nominal AstroGeo22 solution vs time (in Ga). The shaded blue is the estimated uncertainty of the solution. The available quantitities are
– precession frequency ( in arcsec/yr)
– precession period ( in kyr)
– semi-major axis of the Moon (i.e. Earth-Moon distance), in Earth Radius ( RE = 6378.1366 km)
– semi-major axis of the Moon (i.e. Earth-Moon distance), in 1000 km
– length of the solar day ( in hours)
– obliquity of the Earth ( in degrees)
The plot can be panned and zoomed. The final plot can be saved in various formats (pdf, png, svg), ready for inclusion in a presentation or publication.
Warning : The uncertainty that is plotted here is the uncertainty on the parameters of the model. It does not include the uncertainty on the model.
