A general indicator of the residual error for the whole network. Time series for each of the above four cases are given. When the user right clicks on the graphs and selects "Series", two other series are available:
1. Average Satellites Used (showing the average number of satellites used to compute the Single Base RMS).
2. Average Corrected Satellites used (showing the average number of satellites used to compute the Network RMS, for all the satellite systems).
The satellite count scale is available on the right hand side of the graph.
