All participants are being invited to partake in the HALA research network forums on specifics issues in the white paper. The HALA white Paper is in its final stage of completion and the contributions of participants will be the final input to the document to make it official guide for the research network activities. This and other forums have been started on different issues concerning the white paper on the HALA website for this purpose.

• When is a given set of trajectories declared incompatible?
