About grid step

[DrikoldLun]

Hi, I'm a student in Geophysics major, and I'm trying to use your code here to conduct the ambient noise tomography for my research. The minimum limit of the grid step (1°) is mentioned in the menu, and I have found the grid step of initial 2D model can't be set below 1° as well. I want to know if there is any way to reduce the grid size for higher resolution (especially for the high-frequency component)? I will be so appreciate if you can help me.
