Alignment of the Giza pyramids with data measured by Sir W. M. F. Petrie [6] (distances in m). Two numbers have been slightly corrected: The long diagonal is 936.16 m rather than 936.19 m, and one angle is 31° 55' 13' rather than 34° 10' 11' (explanation in [5, p. 96; 6, p. 125]). The relative elevations stem from S. Perring (see: [9, part IV, map 1]). Detailed information is provided in the drawings of Maragioglio and Rinaldi [9]. The angles were calculated from the original distances, given in inches (1 inch = 2.54 cm).
