Template:Dimensionless Hubble constant/doc
 | This is a documentation subpage for Template:Dimensionless Hubble constant. It may contain usage information, categories and other content that is not part of the original template page. |
Description
[edit]Many properties of cosmological objects are reported with the addition of the dimensionless Hubble parameter h. This template addresses only the inverse Hubble parameter h−1
0.70 (since h0.70 is more straightforward to wikicode). If no subscript is specified, then the reader may choose a value of h of their liking to modify whatever the reported measurement is. If a subscript is specified, then the property being reported has been modified by the value of that subscript. For example, 7×1013 h−1
M☉ = 1014 h−1
0.70 M☉.
Our best measurement, as of 2013, for the Hubble parameter is h = 0.6780 ±0.0077 from the Planck mission. In early 2011 it was 0.704+0.013
−0.014 from WMAP 7-year data.[1] See Hubble's law#Determining the Hubble constant for the most recent value of H0.
Usage
[edit]Instead of writing ''h''<small>{{su|p=−1|b=0.6780|a=l}}</small>, one can simply do the following (a numerical subscript is now optional):
{{hub|0.6780}}→ h−1
0.6780{{hub|0.75}}→ h−1
0.75{{hub}}→ h−1
Options
[edit]To include a link to Hubble's law#Dimensionless Hubble parameter, use the |link= parameter. It is optional and defaults to not-used, <blank>, or <null>. It is activated by "yes", or any text:
