What is the zero point magnitude used for?
The zero point is used to calibrate a system to the standard magnitude system, as the flux detected from stars will vary from detector to detector. Traditionally, Vega is used as the calibration star for the zero point magnitude in specific pass bands (U, B, and V), although often, an average of multiple stars is used for higher accuracy.
What is a Zeropoint?
It is the setting of the zeropoint, then, which determines the connection between observed counts and a standard photometric system (such as Cousins RI), and in turn between counts and astrophysically interesting measurements such as the flux incident on the telescope. Zero Points and Apertures
What is the zero point of an instrument?
The zero point of an instrument, by definition, is the magnitude of an object that produces one count (or data number, DN) per second. The magnitude of an arbitrary object producing DN counts in an observation of length EXPTIME is therefore:

The Zodiac is the name of the virtual belt in which the planets, Sun, and Moon appear to move about the sky. In reality, the planets and their respective moons (most of them anyway) orbit the Sun about the same plane. Because the orbits of the planets are not on a perfect plane, the Zodiac band is 16 ° wide – 8 ° on either side of the ecliptic.
