Simulated dataApproximate K from total-field range, K9 = 500 nT — not an official index. Computed from the temperature-compensated network median where a fit exists.

Raw correlation, spikes included — a handful of isolated spikes can swing r hard; compare stations with each other, not with a fixed value. Blank cells: fewer than 30 overlapping samples.
Stations report sensor-frame components; only a station declared as oriented exports geographic X, Y, Z — the rest export F only, with X/Y/Z marked not observed in IAGA-2002. K here is approximated from total-field range and is not an official index. Temperature coefficients fitted across a whole day absorb part of the daily geomagnetic variation; a night-only fit is the honest one.
