I entered wrong tube spacing for one or more profiles in the field. Is there any way of correcting that?

Yes, but this correction can only be made using the CHA-W software version 2007.011.B (dated 3/1/2007) or later. Even though this application allows changing the tube spacing of an individual profile by using the Properties button, as described in the manual, it is important to make sure that the new spacing configuration is geometrically correct. The recommended procedure therefore is to use the Project Integrity Analyzer described here, especially on data that will be submitted to Tomography analysis with the PDI_TOMO program. If you are using the CHAMP you have to transfer the data to a computer and read the data with the CHA-W software application.
