Added initiall and final divergence bandwidths
...
For VEML tracking with Subcarrier Aiding (SA) we start with a reasonably
large uncertainty in the code/subcarrier divergence due to the side-peak
ambiguity problem. However, once we have pulled in, we expect the
dynamics of the divergence to be low. So the final bandwidth can be very
small.
