Data are typically sampled at 2 Hz (up to 8Hz for campaigns). Noise of 0.5 nT peak-to-peak at 5 mHz. 6 dB/octave frequency response to 0.2Hz, then constant with frequency. Daily calibration between 16:30 – 16:40 UT. Timing linked to GPS. Accurate within 50 ms. Data recorded continuously from 1994. H and D components recorded. Data are currently available by request to: firstname.lastname@example.org. Summary dynamic spectra are available. Data must be calibrated if physical units [nT] are required.
