Residual-Regional Separation (FTG)

in Oasis montaj

Hi all, a new learner here. I am working on FTG data on Oasis montaj and still familiarizing myself with the geophysics workflow. I want to separate the residual-regional anomalies of the FTG data. This can be done by wavelength filtering, right? However, I am confused on how to decide the cut-off wavelength for filtering. I read somewhere that the wavelength ranges can be determined using Spectral Analysis. How do I do this on Oasis montaj?

    Hi SyifaSukri,

    You can use the 2D Filtering > MAGMAP Filtering options to apply the wavelength filters you require. You would need the Oasis montaj Processing bundle to have access.
