zenith distance's Usage Examples:

"parallactic instrument" and seems to have used it to determine the zenith distance and parallax of the Moon.

They are used for the measurement of small differences of zenith distance, and used in the determination of astronomic latitude.

By subtracting this figure from 90°, he would find that the zenith distance of the Sun is 0°, which is the same as his latitude.

The microscopes on the limb are then read off, and thus the apparent zenith distance of the collimating point, intersection of the wires, is found.

The true zenith distance of the object is also the distance (in arc) on the Earth's.

distance equal to the zenith distance of the body.

Center = geographical position of the body: (B, L) = (Dec, GHA) Radius = zenith distance: zd [nm] = 60 ⋅.

expanded as a series of odd powers of (tan Z), where Z is the observed zenith distance.

The colatitude is most useful in astronomy because it refers to the zenith distance of the celestial poles.

position is equal to the zenith distance of the Sun at noon on the equinctial day.

The effect of solar parallax on zenith distance was known to Indian astronomers.

The diagram on the right shows why the zenith distance of a celestial body is equal to the angular distance of its GP from.

observing a star and the reading corresponding to the zenith was the zenith distance of the star, and this plus the colatitude was the north polar distance.

It is used to measure specific measurements of the sun such as the zenith distance, declination, and diameter of the sun.

image falls on a scale below enabling the observer to measure the zenith distance, declination, and the diameter of the Sun.

distance between the observed pointing and the sun, Θs is the solar zenith distance (90° – solar altitude), Θ is the angular distance between the observed.

Portuguese mariner's astrolabes are unique because they are graduated for zenith distance only.

may also be mounted vertically above each other in a tower, if the zenith distance of the Sun is greater than zero, and the tower can be turned horizontally.

Elevation: the angular height of an object above the horizon, Alternatively zenith distance, being equal to 90 degrees minus elevation.
