The components X (Northward), Y (Eastward), and Z (Downward) are provided. Components X and Y are calculated from the source records of H (horizontal component) and D (declination); component Z is recorded directly. Additionally, the quantity G is provided — the difference between the mag... 10.2205/IRT2023def https://esdb.wdcb.ru/doi/2026/irt2023def.html 10.12737/szf-71202104 Mishin, V., Karavaev, Y., Lunyushkin, S., Penskikh, Y., & Kapustin, V.
