 # ## Summary Plot
 # 
 # The following plot just summarises the observation simulation efforts of this example. You could go on to reduce the residuals to several meters (see [Kuchynka et al., 2012](https://ipnpr.jpl.nasa.gov/progress_report/42-190/190C.pdf) for details). This indicates some small but important imperfections in our algorithms, for instance simplifications used in the time conversions between the time stamps in the files, and the times used in our simulations. The residuals indicate (among others) a periodic trend at the Earth's orbital period around the Sun.
