Constants & variables

var int igrf14_max_degree #

Highest spherical-harmonic degree IGRF-14 publishes.

var std::size_t igrf14_slots #

Flat coefficient slots: one per (n, m) with n = 0..13, m = 0..n, at index n*(n+1)/2 + m.

var std::size_t igrf14_epoch_count #

Number of tabulated epochs (1900.0 … 2025.0, every 5 years).

var std::array< double, igrf14_epoch_count > igrf14_epochs #

The tabulated epochs, in decimal years, ascending.

var std::array< std::array< double, igrf14_slots >, igrf14_epoch_count > igrf14_g #

The g Gauss coefficients in nT, [epoch][slot]; see igrf14_epochs and igrf14_slots.

var std::array< std::array< double, igrf14_slots >, igrf14_epoch_count > igrf14_h #

The h Gauss coefficients in nT, [epoch][slot]. Slots with m = 0 are 0.0 by definition.

var std::array< double, igrf14_slots > igrf14_g_sv #

Predicted secular variation of g for 2025.0-2030.0, in nT/year. Zero above degree 8.

var std::array< double, igrf14_slots > igrf14_h_sv #

Predicted secular variation of h for 2025.0-2030.0, in nT/year. Zero above degree 8.
