[Seisunix] Help With Residual Moveout

To whom it may concern, Greetings! I need help with the codes for residual moveout. I have done normal moveout correction. I have rms, interval velocities and corresponding depths for some selected cdps. As far as I found from sumanual paper on internet, I need to use surelan command for residual moveout but could not find any information regarding the input parameters and other necessary concepts. I need an image which shows the variation of velocities with different colors in each layer. Please help me out. Thank you. Sincerely, Elora Afrin
