| File:Edit-copy green.svg | This is a documentation subpage for Template:Infobox globular cluster. It contains usage information, categories and other content that is not part of the original template page. |
Infobox for articles on globular clusters.
Usage
Fields should generally be directly from the source, such as SIMBAD. Wikilinks and expansion of abbreviations are acceptable.

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 | Credit for the photograph in the image field. |
| 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 mid-point. The {{RA}} template should be used here. For example: {{RA|hh|mm|ss.dd}}.
|
| dec | The declination coordinate of the cluster mid-point. 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. |
| 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_ly | |
| 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_ly | This is the Roche limit of the cluster, beyond which stars and material are effectively removed from the cluster. The distances can be combined into a single field as: {{Convert|d.dd|kly|kpc|abbr=off|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. |
| 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. |
