Electrical resistivity tomography data

ERT data includes the indices for electrodes a, b, m, and n, where a and b are current electrodes and m and n are potential electrodes. These indices reference the electrode positions file. Raw ERT measurements can include the voltage (u, volts), current (i, amperes), electrical resistance (r, ohm), apparent resistivity (rhoa, ohm-m), and measurement error (err, %).
