We prove two small results on the reconstruction of binary matrices from their absorbed projections: (1) If the absorption constant is the positive root of x2 + x – 1 = 0, then every row is uniquely determined by its left and right projections. (2) If the absorption constant is the root of x4 – x3 – x2 – x + 1 = 0 with 0 x
