4.1.5. IP Inversion¶
The program ipsen3d_55.exe constructs the sensitivitiy matrix for the linearized IP inversion.
4.1.5.1. Running the Program¶
To run the executable, open a command window and type the following:
Essentially you are calling the path to the executable followed by the path to the input file .
4.1.5.2. Units¶
IP data: Depends on the IP data type set in the observations file, the data are either secondary voltage or apparent chargeability
Background conductivity model: S/m
Chargeability model: intinsic chargeability - unitless from [0,1)
4.1.5.3. Output Files¶
The program ipsen3d_55.exe creates the following output files:
ipinv3d.mtx: binary file containing the sensitivity matrix for the IP inversion
ipsen3d.log: log file for the program
sensitivity.txt: the average IP sensitivities of the cells for the models provided.
obs.loc: if the survey file used surface format, the code will output a general locations file that contains the elevations of the electrodes projected to the discrete topography.
