When I have imported a gigapan and look at the results in the control point editor, I often see many "bad" links that only have one control point in them. Usually the control points are in the right place so the link is not bad per se. Is it the case that the algorithm for computing an RMS is inappropriate when there is only one pair of control points or is the RMS still meaningful?
Under the assumption that the RMS is not meaningful, could you devise some way of filtering out these links so that it is easier to see where the real bad links are? Eg a checkbox next to the "Hide links below ..." that hides all links made from one pair of control points.
It needs some explaination. You can see that all links have just one Cp. We used that trick to add artificially some cps on orphan images. So when optimizing the gigapan, these false links are following the images that have real links. But these links are just here for that trick, they doesn't really count for the optimization ( 1 Cp versus 50 cps in average ), there are 50x weaker than true links. So it's a trick, but in practice it works pretty well even if it tends to pollute the link editor.
Thanks Alexandre. Would it be possible to have some way of hiding these false links? Like a checkbox as I suggested? They get in the way of the task of finding the real bad links, and in a gigapan with several hundred images, this is a problem.

But then people will be tempted to try and place new CPs to create links where none appear to exist?
How about having/adding a new colour for such links and having a way for a user to choose not to diplay them?
