where x ≡ ln x for any variable. The expression in ( ) is useful because I see that it has the same functional form, simply displaced in the p∞ -Qm plane. Specifically, one can use the approximations ( ) and (6) to see that (7) will approach straight lines in the limits of infinitely negative and positive Qm with slopes of 1 and 1/2 respectively, which I will refer to as line A and line B. The first terms of ( ) and ( ) also reveal that the intercept of line A will relate to 2/G m and that of line B will relate to 2πC m /n 2 c,m G m (see figure ). While one could potentially fit such straight lines to the data individually, such a procedure could be ambiguous and yield wildly different results than fitting the data to (7). 4 Results and Analysis
