decrease the condition number of bounding ellipsoids #233

Hi,

In my tests (I'm running fits of tens of thousands fits), I still managed to hit an occasional 'can't construct the ellipse bounding points' error, so I've lowered the threshold condition number when trying to improve the matrix to 1e12 (i.e. 1e6 axis ratio). That seemed to have solved it for me.

I hope that won't need more changing...
