minos_bran not working for some long periods calculation

[zheng-xing]

Hi there,

Recently I'm using the latest mineos1.0.2 for Mac and also windows version to calculate the phase velocity for fundamental mode Rayleigh waves. And I found that it does not working for some long period modes even though in the mineos manual it claims "works fine for low frequency application". Specifically, for the mode 000S029 it could not calculate the phase velocity.
One weird thing is on the "play_mineos" website "http://stuplots.geophys.uni-stuttgart.de/~plots/Modes/modes.html", it can give the right answer.
Could someone help identify the where the problem come from? Thanks.
