4.1.6. ZTEM Data¶
ZTEM data can are contained within a Z-axis Tipper EM data object (ZTEMdata). The data columns, properties and functionality associated with these items are as follows:
X, Y and Z: These are columns for the Easting, Northing and vertical position respectively.
Frequency: The frequency at which each datum was collected.
TZXR, TZXI, TZYR, TZYI: For apparent resistivity and phase data (APPdata), these columns represent the real and imaginary components of the elements of the transfer function.
Rx station ID: For the E3DMT version 2 code, each observation location has a set of receivers which is given an ID number. This column contains the station ID numbers for each datum.
Base station ID: This column contains the base station ID numbers for each datum.
ZTEM data type: A flag which determines whether a base station is used when modeling ZTEM data
