    I believe the point you refer to is the transition point from the pressure gradient to pressure recovery phases. This is also the point of maximum airspeed and minimum Cp.

    Have a look at: http://mail.tku.edu.tw/095980/airfoil%20design.pdf

    A well written article that I believe covers what you’re looking for. I’ve not come across any other definitions to fit your question, but I will take a look through some books when I’m home to see if there is perhaps another term you’re searching for.
