Infobox for articles on galaxies.

z, h_radial_v, gal_v
The  parameter (z) can either list the radial velocity of the galaxy in units of km/s, or the dimensionless quantity z. The former is used when the value of z has a very small value, such as less than 0.1.

The parameter gal_v 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 can list the distance in both light-years and parsecs by using the Convert template. For example: gives: 2810 +/-
 * 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 located in.

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:
