Message:

this is an important change. I have changed the way in which the psf
elliptical contour parameters are defined and fitted. SXX,SYY ->
1/SXX,1/SYY (ie, they are now ~ sigma, not ~1/sigma). SXY is now
fitted with the form SXY/(1/SXX^{2 + 1/SYY}2)²

also added some additional tests and checks
