NOTES: The data herein were synthesised from a combination of
experimental results and computer calculations.
The original report contains data for lower Reynolds numbers
than contained herein, but there are some anomalies, in
particular with CL at small angles of attack.
Data extended to 360 degrees of attack and glaring anomalies
corrected by L. Lazauskas. All deviations from the original
are due to L. Lazauskas.
Please refer to the original report for more details.
