Each Constellation object represents a constellation visible on a star map. A constellation consists of one or more imaginary “lines” between stars.
Each Constellation object represents a constellation visible on a star map. A constellation consists of one or more imaginary “lines” between stars.
Parameters
- lines
-
one or more pairs of stars; each pair defines an imaginary line between two stars
- name
-
the name of the constellation

Each Star object represents a star on a star map. It records some basic information (an identifier, a location, and a magnitude); in addition, some but not all stars have been assigned a name. (In reality, many stars have multiple alternative names, but this class does not capture that fact.)

Parameters
- coords
-
the location of the star on a two-dimensional star map
- id
-
a number that uniquely identifies the star from the other visible stars (a so-called Henry Draper number)
- magnitude
-
the apparent magnitude (brightness) of the star: smaller means brighter!
- name
-
the star’s name (wrapped in
Some), orNone

A StarCoords object describes the location of a star on a two-dimensional star map. A location consists of two components, x and y, each of which has a value between -1.0 and +1.0. The x coordinate ranges from -1.0 at the very left of the map to +1.0 on the right; the y coordinate similarly ranges from -1.0 at the bottom to +1.0 at the top. For instance, a star with StarCoords of (0.0,0.0) appears at the exact center of the map.
