Figure F-1. VISUAL ESTIMATION VS. ACTUAL MEASUREMENTS. These scatter diagrams show the esti- 

 mated and the measured dimensions of icebergs sized during the IIP June 1987 iceberg deterioration study. The 

 linear regression is the solid line; its equation (in which Y = estimated feet and X = measured feet) and its correla- 

 tion coefficient are in the upper lefthand corner. The ideal condition (estimated = measured) is shown by the 

 dashed line. 



Figure F-1 a compares estimated vs measured lengths; Figure F-1 b compares heights.
