I would like to ask where the bold expression is coming from?
To calculate the source depths:
Database Tools > Channel math.
Enter the Expression: C0 = (-C1)/(4*3.14)
Assign channels: Enter a new name for C0 and select the gradient channel as C1.

Thank you all.

Hi @MuhammadHanif, From within Oasis montaj, if you go to Help > Applications > Then search for "2D Fast Fourier Transform Theory" there is an explanation of this equation.
Also, here's a link to a very complete paper referencing depth estimates for various scenarios where the same expression is explained, formula 35 on page 16:
Spectral Analysis of aeromagnetic profiles for depth estimation principles, software, and practical application
