EopEntry

Defined in: entry.rs:11

pub struct EopEntry {
    pub mjd: f64,
    pub xp: f64,
    pub yp: f64,
    pub dut1: f64,
    pub lod: Option<f64>,
    pub dx: Option<f64>,
    pub dy: Option<f64>,
}

A single EOP data point at a specific MJD.

All values are in the units expected by arika’s EOP traits:

• xp, yp: arcseconds
• dut1: seconds (UT1 - UTC)
• lod: seconds (excess length of day)
• dx, dy: milliarcseconds (nutation corrections wrt IAU 2000A)
