Helping a friend with his question about airfoils.

"My supervisor told me to get the airfoil geometry of Naca4606, Naca5605 and Naca6605. He also gave me the task to get the airfoil geometry of cambered-thin4602, cambered-thin5602 and cambered-thin6602. Are the cambered-thin airfoils different from Nacas? What’s the main difference and how I can get the airfoil geometry of the cambered thins ? Because in the UIUC airfoil database, I couldn't find them."
