Figure 1.10: Two examples of formal errors on abscissae as assigned in the final
merging of the FAST and NDAC data (large blue dots). On the left, an orbit with
large systematic errors left in the abscissa residuals, on the right an orbit which
performed better in the reductions. Both graphs show in the background, as small
red dots, the formal errors that were assigned to data from these same orbits in the
new reduction.
