TemplateData for Extrasolar planet counts

Centralizes the counts of verified extrasolar planets and systems

Template parameters[Edit template data]

Parameter		Description	Type	Status
data field	1	Specifies the data value to be inserted Suggested values Journal Book Newspaper Magazine	String	required
format code	2	Controls the format for as-of data Default DMY Example MDY	String	optional
data source	source	Switches the data source as reference Suggested values NEA Default EPE	String	optional

The first parameter can be assigned these data values:

• asof: The date as of which the data is valid. With asof only, a second parameter can be specified indicating the format of the date to be inserted. {{date}} is used, and the format codes are defined there.
• planet_count: The number of extrasolar planets
• system_count: The number of systems with extrasolar planets
• multiplanetsystem_count: The number of systems with more than one extrasolar planet; The number of systems needs to be calculated by adding (number of planets in n-planet systems)/n for n up to 8.
• ref: Adds a reference to The Extrasolar Planet Encyclopaedia Catalog Listing
• full: If the entire message displayed on this template is desired
