The general approach thus provides
a total: 1:117 ≤ F_{e} ≤ 1:39 1:808 ≤ F_{gae} ≤ 1:269 The Drakecorrected Special Basic Model 9.6.1 provides: 1:156 ≤ F_{e} ≤ 1: 52 1:1.078 ≤ F_{gae} ≤ 1:359 The Seagercorrected Special Basic Model 11.2.1 provides: 1:100 ≤ F_{e} ≤ 1:31 1:691 ≤ F_{gae} ≤ 1:214 This makes it possible to determine the maximum limits for the probability of a second Earth:
