Two vertices of a triangle \( ABC \) are \( A(3,-1) \) and \( B(-2,3) \), and its orthocenter is \( P(1,1) \). If the coordinates of the point \( C \) are \( (\alpha,\beta) \) and the centre of the circle circumscribing the triangle \( PAB \) is \( (h,k) \), then the value of \( (\alpha+\beta)+2(h+k) \) equals
