ZEDI Zenith distances
Columns | format | contents/explanation |
|---|---|---|
1-4 | A4 | ZEDI |
5-20 | A16 | Station point |
21-36 | A16 | Target point |
37-46 | F10.0 | Zenith distance in gon |
47-56 | F10.0 | Standard deviation of the zenith distance |
57-66 | F10.0 | i - t (height of instrument minus height of target) |
If the standard deviation of zenith distances is missing, the standard deviation of the preceding zenith distance is used.
The program automatically corrects earth curvature and refraction. If the correction is to be omitted or different values are to be used, a CONS statement is necessary.
