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.
