Parameter documentation[edit]
| 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: |
| 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. |
