Application Notes

This dialog option is used to extract windows of information from array channels. For example, this dialog can be used to extract radiometric windows from 256 channel radiometric windows.

The output window is the simple sum or average of values in the array window. If any array values are dummy, the result will be dummy.

If the output channel does not exist, it will be created using the data type of the input array channel.
