Proposition 3.3.

(Leading order asymptote) The formulae for α¯i\bar{\alpha}_{i} are explicitly given as

(3.6) {α¯1=12​a22​{log⁡2−γE−log⁡(1A​|(μ1,μ2,y)|a′−a22A​(μ2+a12a22​μ1))}α¯2=12​a11​{log⁡2−γE−log⁡(1A​|(μ1,μ2,y)|a′−a11A​(μ1+a12a11​μ2))}α¯3=12​a11+2​a12+a22{log2−γE−log(1A|(μ1,μ2,y)|a′+a11​μ1+a12​μ2+a21​μ1+a22​μ2A​a11+2​a12+a22)}\begin{cases}\bar{\alpha}_{1}=&\frac{1}{2\sqrt{a_{22}}}\{\log 2-\gamma_{E}-\log\left(\frac{1}{\sqrt{A}}|(\mu_{1},\mu_{2},y)|_{a}^{\prime}-\frac{\sqrt{a_{22}}}{\sqrt{A}}(\mu_{2}+\frac{a_{12}}{a_{22}}\mu_{1})\right)\}\\ \bar{\alpha}_{2}=&\frac{1}{2\sqrt{a_{11}}}\{\log 2-\gamma_{E}-\log\left(\frac{1}{\sqrt{A}}|(\mu_{1},\mu_{2},y)|_{a}^{\prime}-\frac{\sqrt{a_{11}}}{\sqrt{A}}(\mu_{1}+\frac{a_{12}}{a_{11}}\mu_{2})\right)\}\\ \bar{\alpha}_{3}=&\frac{1}{2\sqrt{a_{11}+2a_{12}+a_{22}}}\{\log 2-\gamma_{E}\\ &-\log\left(\frac{1}{\sqrt{A}}|(\mu_{1},\mu_{2},y)|_{a}^{\prime}+\frac{a_{11}\mu_{1}+a_{12}\mu_{2}+a_{21}\mu_{1}+a_{22}\mu_{2}}{\sqrt{A}\sqrt{a_{11}+2a_{12}+a_{22}}}\right)\}\end{cases}
