Infobox for articles on galaxies.

The parameters whose title has "(V)" or "(B)" refer to visible or bolometric values.

z, h_radial_v, gal_v
These fields provide radial velocity values for the galaxy as a whole. The dimensionless quantity  is the redshift parameter and is used when the value is very small, such as less than 0.1. The  gives the heliocentric radial velocity of the galaxy in units of km/s. The parameter  refers to the galactrocentric radial velocity (the radial velocity relative to the Milky Way), which can be found on NED under the section "Quantities Derived from Redshift" if one looks up a galaxy.

dist_ly
The  field lists the estimated distance to the galaxy in both light-years and parsecs. To do so, use the cvt template. For example:
 * hub identifies the dimensionless Hubble parameter used in the distance measurement. Using NED's default value of 0.73,.
 * if distance is left in 'units' of h.

group_cluster
The parameter group_cluster refers to the galaxy group or galaxy cluster that the galaxy is a member.

type
The parameter type is the de Vancoleurs morphological type of the galaxy. These can be found on NED or SIMBAD. (Note that a  in NED is actually a superscript, so for example S0^0 should be written as S00 .)

In SIMBAD the morphological type is often given as a number between -6 and 11. To convert these into the de Vaucouleurs class, use this table from this article:

appmag_v, appmag_b, absmag_v
The  give the apparent magnitude of the galaxy in the visual band, while   gives the same in the B (blue) band. The  is the absolute magnitude of the galaxy.

size_v
The  field lists the visual angular size of the galaxy along the major and minor axes, given in units of arc minutes or arc seconds. For example: 4.3′ × 0.8′. For non-visual dimensions, the band should be also listed, such as (IR) or (UV).

names
This is a list of catalog identifiers for a galaxy, preferably presented using the odlist template.
