Table 3 The comparison between Hohenkerk’s calculation results and those in this paper, for the apparent zenith distance is less than \(70^{\circ }\), \(\lambda\)=0.574 \(\mu\)m and \(h_0\) = 0. (unit: arcseconds).
Zenith distance | Hohenkerk | This paper |
|---|---|---|
\(10^{\circ }\) | 10.27 | 10.05 |
\(30^{\circ }\) | 33.61 | 32.90 |
\(45^{\circ }\) | 58.17 | 56.94 |
\(60^{\circ }\) | 100.53 | 98.37 |
\(70^{\circ }\) | 158.66 | 155.18 |
