Could I add an idea to this. One of the neat features in Guide, is the
ability to plot the contents of an MPC (Minor Planet Center) data file.
When the asteroid trail is displayed with the MPC data points, serious
observational errors become obvious. But only positional errors.
Timing error can't be seen with this method. If some connection could
be made between the times of the observations and the times of the
trail, then timing errors would also become appearent.
