Figure 3From: In-flight performance of the Absolute Scalar Magnetometer vector mode on board the Swarm satellitesExample of an in-flight-detected ASM sensor heater perturbation. Temporal visualization (top graph) of high-pass-filtered ASM scalar burst data in nT for ASM FM1A from 14:17:48 to 14:17:56 on Swarm Alpha and corresponding amplitude spectrogram analysis performed on a 64 FFT size (bottom graph: DSP amplitude in pT versus frequency and time).Back to article page
