¥MT data consist of:
–3 components of magnetic field (Bz, Bx, By)
–2 orthogonal comps. of electrical field (Ex, Ey)
–Timing, system temperature, status,
etc.
¥Recorded at 1 Hz sampling
¥Electric field is measures with grounded dipoles
ranging from 25m for temporary deployments,
up to 10,000m in length for permanent
stations.
