The use of RADARSAT-2 to monitor shipping would be a question best passed to the Department of National Defence, but I can speak to the collaboration that we have with the Department of National Defence.
If I'm using RADARSAT-2 in a particular mode to look for sea ice or oil pollution, it's optimized for that. The Department of National Defence perhaps would like to see it optimized to look for ships. So we collaborate to ensure that we come up with ways of programming RADARSAT-2 to do a fairly good job on both. Consequently, we do see ships.
I'll say this about RADARSAT-2: it's very good.
