In this paper we consider diagonally affine, planar IFS Φ = = S i (x, y) = (α i x + t i, 1, β i y + t i, 2) i = 1 m \Sᵢ (x, y) \!=\! (ᵢx+t₈, ₁, ᵢy+t₈, ₂) \₈=₁ᵐ. Combining the techniques of Hochman and Feng and Hu, we compute the Hausdorff dimension of the self-affine attractor and measures and we give an upper bound for the dimension of the exceptional set of parameters.
