Template:Infobox star/testcases

This is the testcases page for {{Infobox star/sandbox}}, used to test changes to the individual features of {{Infobox star}}, prior to their potential integration into the live infobox code. Various detailed examples of the infobox's parameters and features are documented here to provide the information necessary to aid editors' understanding on why and how particular features are used, and how the code for their use works. The current version of the complete blank syntax for {{Infobox star/sandbox}} can be found in the "Syntax" section below.

By default, {{Infobox star}} displays a map of a constellation, set by the constellation parameter, which swaps out the name of a constellation in the filename – {{{constellation|}}} constellation map.svg. The placement of the circle which locates a star on a given constellation map is controlled using the parameters map x and map y. These two parameters, along with constellation, are essentially the only parameters needed in order to make the map work, per this case for Aldebaran. This is achieved with two <div> phrases that appear in the image parameter of {{#invoke:InfoboxImage}}.

"image", "caption", and RS Puppis

While constellation maps may be useful in locating a star, sometimes stars can be recognisable in their own right, due to either their proximity to other celestial objects or their prominence in a particular region of the sky. RS Puppis is one such example where the star is surrounded by a large, bright nebula, thus making it a recognisable sight among astronomers and astronomy fanatics. In this case, the default parameters map x, map y, and map circle are removed completely, and replaced with image, alt, and caption to display "Heic1323a -1243686232.jpg" with a relevant caption and alt caption. This is achieved with two {{#if:}} parser functions – one replaces the two <div> phrases used to make the constellation map possible with a simple {{{image|}}} parameter if image is active, and the other checks to see if either the image or map image parameters are active before activating the caption parameter.

"map image" and Kepler-90

Kepler-90

Star in Draco
Epoch	J2000.0
Coordinates	18h 57m 44.0384s +49° 18′ 18.4958″
Apparent m (V)	14.0
Absolute m (V)	~4.3
Distance	2840±40 light-years

In some cases it may be appropriate to use a different image for the infobox's map. Kepler-90 is a star that is part of the Kepler field of view, an area that is mostly situated in, and mostly associated with, the constellation of Cygnus. However, Kepler-90 is not only in the constellation of Draco, it's far away from any of the major features of Draco. Being closer to one of the 'wings' of Cygnus, it would be better illustrated in relation to Cygnus instead, thus the map image parameter is being used here to replace the default map of Draco, called by the constellation parameter, with "Cygnus constellation map.svg" instead. This is achieved with an {{#if:}} parser function that replaces the default {{{constellation|}}} constellation map.svg string with {{{map image|}}} when it finds the map image parameter active.

"map circle" and Maia

Maia

Maia (circled) in the Pleiades
Star in Taurus
Epoch	J2000.0
Coordinates	03h 45m 49.6067s 24° 22′ 03.895″
Apparent m (V)	3.871
Absolute m (V)	−1.69
Distance	~400 light-years
Proper motion	21.09 mas/yr −45.03 mas/yr
Radial velocity	7.5 km/s
Characteristics
Age	75–150 million years
Mass	>5 solar masses
Radius	6.04 solar radii
Temperature	12,600 kelvin
Stellar class	B8III

In various situations where the image used in map image does not work well with the map circle's size, its width can be changed to make it better stand out against the image. With Maia (star), an image of the Pleiades cluster is used to locate the star, though the circle's default width of 12 pixels is not wide enough to properly encircle the star in the image. Thus, map circle is used to bump up the circle's width to 25 pixels instead. This is achieved by setting a default value on the parameter itself – {{{map circle|12}}}px – which is ignored the moment the parameter is used and a different value is placed in it.

"apparent alt" and the Pistol Star

Pistol Star

Infrared image of the Pistol Star (center) and the surrounding Pistol Nebula
Star in Sagittarius
Epoch	J2000.0
Coordinates	17h 46m 15.3s −28° 50′ 04″
Apparent m (V)	>28
Apparent m (K)	7.291
Distance	~26,000 light-years
Radial velocity	>130 km/s
Characteristics
Age	4 million years
Mass	27.5 solar masses
Radius	306 solar radii
Temperature	11,800 kelvin
Variable class	Luminous blue

Natural phenomena can make certain stars more notable for their apparent brightness in different regions of the electromagnetic spectrum. For example, the Pistol Star is notable for being practically invisible to the human eye, but shining prominently in infrared light. In this case, the parameters apparent band and apparent alt are used to include information on the star's apparent magnitude in the K band. This is achieved with an {{#if:}} parser function that activates this second apparent magnitude cell only if apparent band is active.
