Can they be effectively used in searching for derilicts? Bertil suggested I should post the following table which he typed in and deleted (we were talking about this topic via mail a week or so ago). I don't remember exactly where he got it from (Grand Survey comes to mind), it was classic trav (I am pretty sure about that).
