"title" means that the coordinates will be displayed next to the article's title at the top of the page (in desktop view only; title coordinates do not display in mobile view) and before any other text or images. It also records the coordinates as the primary location of the page's subject in Wikipedia's geosearch API.
To add Lua error: callParserFunction: function "#coordinates" was not found. to the top of an article, use either
(which does not require minutes or seconds but does require the user to specify north/ south and east/west) or
(in which the north and east are presumed by positive values while the south and west are negative ones).
These coordinates are in decimal degrees.
Degrees, minutes and seconds, when used, must each be separated by a pipe ("|").
