Astronomical Survey

(project to collect uniform astronomical data across the sky)

An Astronomical Survey is a project to gather astronomical data over some portion of the sky, in some cases, all. It may be an image or set of images. Currently, many are done automatically.

The targets may be based upon appearance (e.g., portion of the spectrum at which the object is evident), based upon object type (e.g., galaxies), or may be some aspect of Cosmic Background Radiation (CBR). It can result in an associated Astronomical Catalog and Survey-based Designator.

Surveys are naturally Magnitude-limited, and it is now common for a specific magnitude limit is adhered to as much as possible, to allow for accommodating the Malmquist Bias and similar issues. The magnitude may be listed as a letter indicating the Passband, e.g., k = 19.0 for an Apparent Magnitude (m) of 19 in the K Band.
