Template:Componentbox doc

The templates {{Componentbox begin}}, {{Componentbox component}}, and {{Componentbox end}} are used for listing the components of double and multiple stars and specifying their separation relative to a primary component. The {{Componentbox begin}} template is used first, followed by one use of {{Componentbox component}} for each component, except the primary (assumed to be described elsewhere in the article); {{Componentbox end}} is used to terminate the list.

An example is as follows: 

{{Componentbox begin
|designation=[[Washington Double Star Catalog|WDS]] 00004+7305
|footnote=<ref>Entry 00004+7305, 
[http://ad.usno.navy.mil/wds/wdsnewframe1.html The Washington Double Star Catalog], 
[[United States Naval Observatory]].  Accessed on line August 12, 2008.</ref>
}}
{{Componentbox component
|letter=B|primary=A
|appmag_v=13.0|epoch=2000|angdist=22.8|posang=282}}
{{Componentbox component
|letter=C|primary=A
|appmag_v=11.66|epoch=2000|angdist=44.4|posang=296}}
{{Componentbox end}}

A fuller table, including right ascension, declination and a link to SIMBAD for each component may be displayed by adding the argument expanded = yes to {{Componentbox begin}} and each occurrence of {{Componentbox component}}: 

{{Componentbox begin
|designation=[[Washington Double Star Catalog|WDS]]&nbsp;00004+7305
|footnote=<ref>Entry 00004+7305, 
[http://ad.usno.navy.mil/wds/wdsnewframe1.html The Washington Double Star Catalog], 
[[United States Naval Observatory]].  Accessed on line August 12, 2008.</ref>
|expanded = yes
}}
{{Componentbox component
|letter=B|primary=A
|expanded = yes
|ra = {{RA|00|00|17.36}}
|dec = {{DEC|+73|05|00.9}}
|radec_footnote = <ref>{{SIMBAD link|**+HJ+3231B|CCDM J00003+7305B  -- Star in double system}}, 
database entry, [[SIMBAD]], accessed on line August 13, 2008.</ref>
|simbad = **+HJ+3231B
|appmag_v=13.0|epoch=2000|angdist=22.8|posang=282}}
{{Componentbox component

|dec = {{DEC|+73|05|15.8}}
|radec_footnote = <ref>{{SIMBAD link|**+HJ+3231C|CCDM J00003+7305C  -- Star in double system}},

|simbad = **+HJ+3231C
|expanded = yes
|appmag_v=11.66|epoch=2000|angdist=44.4|posang=296}}
{{Componentbox end}}
