Dear all,
                  we've just completed the ESA review of the current draft 
of Planning Information Formats events and have identified the following 
points and questions.

It would be useful to add the OWLT as an optional parameter to all events
It would be useful to add the elevation angle as a mandatory parameter to 
the FwdComsStartEvent, RetComsStartEvent ,FwdComsEndEvent and 
RetComsEndEvent events (JP would this cause any problems with respect to 
KeyholeEvent should be split into 2, KeyholeStart and KeyholeEnd
Question; should OWLT or RTLT be used ?
Question: How should comms events be handled for Rovers, e.g. define the 
relay spacecraft (or Rover) as an aperture or define specific events for 
Rover visibility or any other ideas ?

Anyway these can be used as input to the PIF discussion in San Antonio.

Cheers for now,
