[MSNoise] MSNoise-Tomo, Parameters

Hey everyone, I'm trying to use the MSNoise-Tomo plugin to compute dispersion curves that I can then use for a simple inversion, but I'm having a hard time to find "good" parameters. Could someone write me what the Bmin, Bmax parameters do and what they're called? Or refer me to a paper/article, where I can read a bit more about the subject. In the papers referenced I could find something regarding beamforming, is that maybe the B parameter? I appreciate gladly any help and references :) Best regards, Jannik
