cheatah-space v0.1.0-alpha — Biome Standard 0.6.5-alpha

The Sun's apparent position, to the accuracy the GSE frame definition needs.

Only the ecliptic longitude and the obliquity enter the transformations — GSE's X axis is the Earth–Sun DIRECTION, so the Sun's distance is irrelevant and its ecliptic latitude is zero by construction of the ecliptic.

Constants & variables

var double mean_anomaly_deg #

var double mean_longitude_deg #

The Sun's mean longitude Λ, in degrees.

var double ecliptic_longitude_deg #

The Sun's apparent ecliptic longitude λ☉, in degrees.

var double obliquity_deg #

The obliquity of the ecliptic ε, in degrees.
