Hi All,

A new version, v1.68, of nbody has just been released. I have not yet released the mac multi-threaded version (OpenMP). I will release this at a later date.

In this release we have added a new way of constraining the width of the stream. Previously, we were using a measure of the velocity dispersion in each histogram bin. This led us to fit our parameters quite well. Unfortunately, we found that this may not be the best method in the long run. I have added a measure of the beta coordinate dispersion which, from initial findings, will be (hopefully) easier to fit our parameters with.

As always, please let me know if there are issues.

Thank you all for your continuing support,
