Summary
This document describes how to setup and invert targets.
Pre-requisites
Inversion
The two functions used for EMI inversion are Create Cells and EM Invert
Create cells
Note: See Processing parameter selection section for discussion of how to choose cell size.
-
The Create Cells configuration window controls the size of the circular data chip that will be inverted.
Create cells dialog box.
EM Invert
Note: See Processing parameter selection section for discussion of how to choose parameters.
- This window sets parameters for the single source inversion (SOI), 2 source inversion (2OI) and 3 source inversion (3OI).
- In general, the inversions should be run in the “-a” data state.
- The time channels used for inversion is controlled by the Default Mask drop down menu. Modifying the selected channels can be accomplished by clicking on the
button. In general, we use the tlate set of channels. - #Candidates: The recommended number of start model candidates is 10.
-
#Start Models: For multi-source inversion (i.e. 2OI and 3OI) there is a preliminary scan for start models. We recommend a minimum of 2000 for this parameter.
