Parameter documentation

Field	Description
name	Common name of the globular cluster. This field is required.
image	Photograph of the cluster. Preferably this should be a wide shot to show most/all of the globular cluster rather than a view from within it. Include the "File:" prefix and a width of 300px. If uploading a new image, please put them on Commons so they can be easily used by the other language Wikipedias.
caption	Description of the photograph in the image field.
credit	Per MOS:CREDITS, credits for the image in the infobox are discouraged since the infobox should only contain key facts of the article's subject.
epoch	The astronomical epoch of the cluster coordinates (below). Normally this is [[J2000]].
class	The Shapley–Sawyer Concentration Class of the cluster.
constellation	A link to the constellation where this cluster is located.
ra	The right ascension coordinate of the cluster midpoint. The {{RA}} or {{Deg2HMS}} templates should be used here. For example: {{RA|hh|mm|ss.dd}} or {{Deg2HMS|dd.ddd|sup=yes}}.
dec	The declination coordinate of the cluster midpoint. The {{DEC}} template should be used here. For example: {{DEC|±dd|mm|ss.d}}.
dist_ly	This is an estimate of the cluster's distance from the Solar System in light years. The distances can be combined into a single field as: {{Convert|d.dd|kly|kpc|abbr=off|lk=on|sigfig=1}}.
dist_pc	This should be the same distance as dist_ly using parsec as the units. A parsec is equal to 3.2616 light years.
appmag_v	The apparent magnitude of the cluster.
size_v	This gives the angular diameter, usually in arc minutes or arc seconds.
absmag_v	This gives the V-band absolute magnitude.
mass_msol	The estimated total mass in solar masses.
mass_kg	The same value as above, using kilograms as units. A solar mass is equal to 2 × 1030 kg.
radius_arcminsec	The angle subtended by the radius, in arcminutes or arcseconds.
radius_ly	The ly and pc radii can be combined into a single field as: {{Convert|d.dd|ly|pc|abbr=on|lk=on|sigfig=1}}.
radius_pc	This should be the same distance as radius_ly using parsec as the units. A parsec is equal to 3.2616 light years.
radius_tidal_arcminsec	The angle subtended by the tidal radius, in arcminutes or arcseconds (specify).
radius_tidal_ly	This is the Roche limit of the cluster, beyond which stars and material are effectively removed from the cluster. Typically given as either the instantaneous value or an average of its perigalactic and apogalactic values. The ly and pc radii can be combined into a single field as: {{Convert|d.dd|ly|pc|abbr=on|lk=on|sigfig=1}}.
radius_tidal_pc	This should be the same distance as radius_tidal_ly using parsec as the units. A parsec is equal to 3.2616 light years.
v_hb	The visual magnitude of the horizontal branch stars in the cluster.
metal_fe	The metallicity as a logarithmic abundance of iron relative to hydrogen, as compared to the Sun.
metal_z	The metallicity as a logarithmic abundance of elements other than hydrogen and helium, relative to hydrogen, as compared to the Sun.
age	The estimated age of the cluster, usually listed in [[Gigayear|Gyr]] (billions of years).
notes	Additional details of significance.
names	A comma separated list of used alternative cluster names. These are names that are commonly used in scholarly journal articles, such as the New General Catalogue (NGC) name.
