The graze zone is typically five to ten kilometers wide and its interior and exterior boundaries can be predicted using the lunar limb profile. Table 6 provides topocentric data and corrections to the path limits due to the true lunar limb profile. At five minute intervals, the table lists the Moon's topocentric horizontal parallax, the semi-diameter, the relative angular velocity of the Moon with respect to the Sun and lunar libration in longitude. The center line altitude and azimuth of the Sun is given, followed by the azimuth of the umbral path. The path corrections to the northern and southern limits are listed as interior and exterior components in order to define the graze zone.
Positive corrections are in the northern sense while negative shifts are in the southern sense.
Corrections to the center line umbral durations due to the lunar limb profile are also included and they are all negative.
