Caslon Pro stylistic sets

Hello, my question is in regard to the stylistic sets that are part of Adobe Caslon Pro.

How can I find out the specifics of which parameters each stylistic set affects?

I am trying to find a style that maintains standard ligatures with the exception of 'Th' and, possibly, 'Qu' as well.

While that is my specific aim, it would also be extremely helpful to know what all of the sets do. I'm surprised that there isn't any easily accessible documentation, considering that they are built right into the font.
