We have a module called "Velocity analysis" in g-Platform which can be used for various purposes. The primary use is
•To pick the velocities (even though we won't recommend it)
•Place before and after Radon analysis module to check the multiple attenuation on the velocity semblance.
Module name Velocity analysis
Similar to Stack Imaging, the user can pick the velocities on the semblance and save the velocity picks from the "Save picking" action item menu.
