%X This data set is produced by kt-400sz (Shenzhen Ketan Electronic Technology Co., Ltd.) field test. This set of equipment is composed of natural electric field detector, special cable for detection, special signal probe, USB data cable, host software, etc.The host and probe are connected by detection cable, and the host is connected with two positive and negative electrodes. The positive and negative electrodes inserted into the earth's surface receive the electrical component of the magnetotelluric field on the earth's surface, and the measured information contains the dynamic information and static information of the natural electric field. According to this, the corresponding mathematical model is established to obtain the details of stratum distribution.The data set contains 98 groups of data, of which each group of data contains 10 data points.
