Plots of modified wavenumber and phase speed vs wavenumber for different schemes. cs-6th is the compact 6th-order tridiagonal scheme studied by Lele [2], and the scheme has the best resolution in the series of 6th-order scheme; cs-8th is the compact 8th-order pentadiagonal scheme [2], and the cs-8th uses the same formula Eq. (22) in spatial discretization as the compact 8th-order GKS
