The material describes the BFO error, difference between logged and calculated BFO, on a test flight described in the text accompanying the figure.

The significance of the above data is two-fold. First there are BFO errors on the order of 20Hz, and second the error is one-sided. Previously Inmarsat suggested BFO accuracy should not be assumed to be better than 7Hz (not clear if this peak, or one sigma). Analysts have been synthesizing candidate paths with low single digit BFO errors. This new data opens up the range of 7th arc solutions rather dramatically.
