Home study course:

Page 5-11 describes how to take the d-correction from Table 5 for box 5. When I work the problems on page 5-18, I do not arrive at the same results for the Hc shown in the intermediate steps in the answers section, though all other intermediate results are identical. Can you walk me through the tab Hc to Hc for problem 3? I find tab Hc of 43 degrees, 00.0 minutes, d-value of -60, and Z = 180, Declination minutes = 59.8, and d-corr = 0.0 minutes, for an Hc of 43 degrees, 0.0 minutes. The answer sections shows an Hc of 42 degrees, 00.2 minutes. Where did I go wrong?

I figured it out after reading in the online course the recommendation to do interpolation.
