When the IAU's value for k is used to calculate these times, they must be corrected to accommodate low valleys or high mountains along the Moon's limb. The calculation of these corrections is not trivial, but is necessary, especially if one plans to observe near the path limits (Herald 1983). For observers near the central line of a total eclipse, the limb corrections can be more closely approximated by using a smaller value of k, which accounts for the valleys along the profile.

当IAU的K值被用来计算这些时刻，他们必须纠正并使其符合月球边缘的低谷和高山，这种修正并不是不重要的，相反是很必要的，特别是计划观察靠近极限路径时（Herald 1983），对于靠近全食中心线的观测者来说，在使用更小K值的情况下，边缘修正会被更准确地近似，这个K值代表山谷沿着轮廓。
