Parameters

redshift

The redshift 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.

dist_ly

The dist_ly field can list the distance in both light years and parsecs by using the {{Convert}} template. For example: {{convert|2810|+/-|90|kly|kpc|abbr=on|lk=on}} gives: 2,810 ± 90 kly (862 ± 28 kpc)
