1. Click the Load button to select a Sectorial STC or DSTC measurement result file.

The following window will pop up:

It allows you to select a file and to load a number of scans out of an S4 plot file.

Click the Find File button to load the data. By default it will point to the RESULTS directory of

the active campaign folder. Select the desired file and click OK. Since only one scan is available, you

don’t need to alter the default scan selection. Just click OK and load the file into a layer of the

inventory.
