(a) Variance of β1,2 as a function of 〈I〉 as computed using equation (12) (solid lines) and simulated values (dots). The variance decreases with increasing 〈I〉 for low signals and then increases again as 〈I〉 approaches 1. (b) Variance of βV as a function of 〈I〉 as computed using equation (13) (solid lines) and simulated values (dots). Note that saturates at high 〈I〉. |
