Description of the various fields in the catalogue

Field: design

Designation in a standardized spelling. The colon behing a galaxy designation means that this name is given to 2 (or more) objects. It may happen in particular for members of a pair or of a group of galaxies. The pair keeps the name given in the catalogue and the 2 objects members of the pair have the same name + the colon.

definition
-1
Not fully reliable name. In the past this name was given to another object of the database (wrong identification), and was corrected to its current affectation. There is a risk that some references in the literature use the ancient wrong identification. This name should be avoided.
1
Unreliable name. This name is associated with a different objects in different papers, and in particular between NED and HyperLeda. It should not be used.
2
Degenerated name. This name is given to more than one object (like maybe the members of a pair of galaxies). It should not be used.
