Pedal sets of unitals in projective planes of order 9 and 16

Let U be a unital in a projective plane P. Given a point P in P\U, the points F in U such that FP is tangent to U are the feet of P, and the set of all such points is the pedal set of P. In this paper we study pedal sets of unitals embedded in projective planes of order 9 and 16.
