Numerical settings ($AnalysisConfig)
workingPrecision 50 Numerical working precision in digits
gridLogMin −20 Lower bound of the pole-search interval in log10 |s|
gridLogMax −3 Upper bound of the pole-search interval in log10 |s|
gridPoints 2000 Number of grid points used to detect sign changes in the secular determinant
omegaInterestMin 10−10 rad s−1 Lower bound of the frequency interval used for dominant-mode selection
