+        A special directive that indicates the IP data type. This directive is only required in IP data files. The IPTYPE enables the IP inversion programs to distinguish the apparent chargeability and other similar IP measurements from the basic secondary potentials.
 
   - ``IPTYPE = 1`` is commonly used for IP data in which apparent chargeability is well defined (i.e. using dimensionless apparent chargeability, integrated chargeability, PFE, or phase data acquired using electrode configurations that do not produce zero crossings in the measured total potential). The following are some examples of this type of geometry: any pole-pole array (surface or borehole), surface pole-dipole or dipole-dipole array along the same traverse, gradient arrays where the potential electrodes are parallel to the current electrodes, or borehole pole-dipole or dipole-dipole array with all active electrodes in the same borehole.
-    
-  - ``IPTYPE = 2`` is used for secondary potential IP data measured using any electrode geometry. This is typically used when cross-line surface data or cross-hole borehole data are inverted. For these array geometries, the apparent chargeability cannot be defined since the total potential can be zero.

   - The dimensionless apparent chargeabilities (``IPTYPE = 1``) and the secondary potentials (``IPTYPE = 2``) can be mixed in the same file. Thus an IP data file can have several occurrences of IPTYPE. All the data are treated as the same type following an IPTYPE directive until a new line changes the type.

To convert the ``DCIPoctreeFwd`` output into an observation file to be used as the input for the inversion code the column of apparent conductivities/chargeabilities needs to be deleted and proper standard deviations need to be assigned.

 If the topography surface is supplied, the cell weights above the surface will be ignored. It is recommended that these weights be assigned a value of ``-1.0`` to avoid confusion. If ``NO_WEIGHT`` is given in the input files instead of the weights file, then all of the cell weights will be set equal (``1.0``).
