Magnitude-size of stars 2Mass, J K H filters, is too long of visual for
correction, and very bad effect size-star for infrared is more diameter that
diameter visual magnitude, result is a false stellar field for compare.
But the information in 2Mass is very usefull.

would be possible an option to disconnect the circles 2mass?
