linear:
This is a simple subtraction method based on the assumption that the background corresponds to a straight line, between the start and end points of the background. This is the default method, for AES and XPS.
This method is generally acceptable where there is not a large change in the background height, however, when there is a large change in background heights this can lead to relatively large errors
