साँचा:Starbox 2

This template is used to display information on a star system consisting of 2 stars. The template should be used as shown below. Unused arguments may be omitted. Arguments containing _a give information for the first component. There are corresponding arguments with _b which give information for the second component. For example, radius_b gives the radius of the second component.

There are four possibilities for displaying the right ascension and declination.

1. Coordinates of the center of mass of the system are displayed, and formatting is done by the template. Use ra_system_h, ra_system_m, ra_system_s, dec_system_d, dec_system_m, and dec_system_s.
2. Coordinates of the center of mass of the system are displayed, and formatting is done by the editor. Use ra_system and dec_system. Use of the साँचा:tl template is recommended for formatting the right ascension, and the साँचा:tl template for formatting the declination.
3. Coordinates of each component are displayed, and formatting is done by the template. Use ra_a_h, ra_a_m, ra_a_s, ra_b_h, ra_b_m, ra_b_s, dec_a_d, dec_a_m, dec_a_s, dec_b_d, dec_b_m, and dec_b_s.
4. Coordinates of each component are displayed, and formatting is done by the editor. Use ra_a_1 and ra_b_1 for the first line of right ascension and dec_a_1 and dec_b_1 for the first line of declination. If a second line is desired (this may narrow the infobox), use ra_a_2 and ra_b_2 for the second line of right ascension, and dec_a_2 and dec_b_2 for the second line of declination. Use of the साँचा:tl template is recommended for formatting the right ascension, and the साँचा:tl template for formatting the declination.

If the argument parallax is provided and dist_ly and dist_pc are omitted, the distances will be calculated automatically from the parallax (and the parallax error p_error, if provided.)
