RMS velocity segy to interval velocity segy

[murray...@gmail.com]

Dear all,

I am trying to convert a segy of RMS velocities into a segy of interval velocities. The end goal of this is to overplot semi-transparently the interval velocities on the final stacked section, such as the example image below. I've been trawling the su help documentation but can't work out if there is a way to do this. Does anyone know of a way to do this simply?

Best,

Murray
