Survey Field

(Survey Region, Field)
(portion of the celestial sphere where a survey's observations aim)

The phrase Survey Field (or Survey Region or sometimes Field of View) is used for the portion of the Celestial Sphere where an Astronomical Survey's observations are carried out. The phrase All Sky Survey means just that, or sometimes just a substantial portion of the sky, e.g., when performed from a single ground location. Surveys often reuse a past survey field to carry out additional observations, e.g., other parts of the Electromagnetic Radiation spectrum, greater depth, or Spectrography. A Deep Field is a small field used for extreme depth, i.e., looking for distant and therefore faint objects.
