Member Data Documentation

◆ magnitude

int lost::CatalogStar::magnitude

The magnitude of the star, with the decimal point shifted two places right.

I.e., multiply this by 10^-2 to get the magnitude.

Definition at line 37 of file star-utils.hpp.

◆ name

int lost::CatalogStar::name

A unique number which unambiguously identifies the catalog star.

The catalog is an array, so in algorithms we usually refer to catalog stars by their index in the catalog. However, if the catalog is filtered (say, to remove stars that are too dim or too close to each other), the indexes change, which makes everything really hard to debug because indexes change based on how the catalog was filtered. That's what names are for: They're fixed and don't change.

Definition at line 42 of file star-utils.hpp.

◆ spatial

Vec3 lost::CatalogStar::spatial

The point on the unit sphere where the star lies.

The earth is at the center of the sphere. A star with right ascension and declination both equal to zero will lie at (1,0,0).
