where I see the first term of ( ) is proportional to (3), with a multiplicative factor of 2. The linear model for p ∞ in discussions below will refer to the first term of (5), rather than Sugimoto's equation (3). It is assumed that C m is independent of Q m for fitting these data since this is a common observation from LaMer burst experiments. In turn, the conditions at nucleation (including n c,m and G m ) should be independent of Q m , so the COP model has two independent fit parameters when data is provided for p ∞ and Q m .
