Note that only TCA (green one edge, magenta the other) can be
corrected with lens profiles.  LCA ("purple fringing") must be
eliminated with other tricks.

If the green/magenta TCA is still visible, you can upload sharp
images with contrasty edges over the whole image (like
http://wilson.bronger.org/lens_calibration_tutorial/DSC03194.jpg) at
http://wilson.bronger.org/calibration and I improve the profile.

What do you mean with this?  That the profile doesn't work well or
that you like the lines still slightly bent?

Tschö,
