  Hi John. Sounds like you've asked something similar in the past that I haven't seen (or I've forgotten) so I don't quite understand your question. Are you asking if this image has been seen by someone else who's already marked the fans, or is it that you have seen it before, or have I missed it completely?

  Hi John, in short the answer is yes someone else has probably looked at it and marked the fans. But you should carry on and mark them anyway. The whole point of the exercise is to get lots of measurements of the size and direction of the fans. The data can then be averaged to get a very good approximation of the right answer.
