Hi Gary, I get a little nervous about re-usability when I see specific numbers (like 300km and -30C) in a definition. They prompt two questions: 1) Is it clear that the community always uses these exact numbers (or so often that they are a de facto standard)? 2) Why is it necessary to say 'to pixels within 300km'? Why isn't the temperature limit enough?
