Closed capture; which p-hat(s) correspond to the pi mixture?

[ges]

I am analyzing breeding bird data using the Huggins Full Closed Capture with Heterogeneity as a removal model with 2 mixtures (analogous to the Farnsworth model in SURVIV, with equal length time intervals). Chapter 14, page 11, in a Gentle Introduction states that the first p-hats represent the first mixture, and the second p-hats represent the second mixture. My question: Does this mean explicitly that the first mixture is always represented by pi, and the second mixture by (1-pi)? Similarly, if I set the first p (or group of ps) equal to 1, and compare this analysis to that performed in SURVIV, where (1-c) represents a proportion with p =1, does the pi in MARK correspond to the c in SURVIV, or does the pi correspond to (1-c)?

Thanks,
Glenn
