Caption: Figure 3.

An example of our background measurements (gray) and empirical OFF model construction (black), represented by the start (top panel) and end (bottom panel) of selected observing scans. These OFF models are used to remove variations in the background signals (Equation (3)). This figure exemplifies the changes occurring in the spectral baseline during a leg of the on-the-fly map, caused by a combination of atmospheric and instrument instabilities.
