OK, attached london-4.pto, mean error 3.0, max 40.1. The process I went through is as follows, in Expert interface, Optimiser tab; 1. 'unselect all' Yaw (y) (right click on column header) 2. 'unselect all' Pitch (p) 3. 'select all' X, Y , Z (image #2 is automatically not selected as it is position anchor) 4. deselect hfov(v) for lens #2 (position anchor) 5.

That works nicely (I rotated it so that North is up), by altering the R of the anchor a little at a time, re-optmising after each change. So - follow-up questions 1) How did you do it?! 2) what are the units of X Y Z (it's clearly not pixels). I'm also most unclear on why, given the nature of this data (and the use of multiple lenses), Z is varying at all. And yet; X and Y only vary between -0.1 and 0.1, but Z runs from -0.5 to 1.2 I'm clearly misunderstanding X Y Z, which is probably why I'm not making good use of the modelling they provide.

Never try to optimise ALL the FOV's, always leave one (perhaps the one on the anchor...) set! I have now succeeded in making an XYZ model from the per-optimised YPR model, but have not succeeded in getting an XYZ model to optimise from a fully reset parameter set.
