[gradsusr] csmooth working on contours but not shaded fields?

I believe you need 'set cterp off' to get the shaded and line contours to align exactly. --Jennifer

I have attached an image where I have the csmooth option 'on' for both a shaded field and contours. You will notice the difference as the contour field is slightly smoother than the shaded field. Both the shaded field and the contours have the same interval. Here is a snippet of the code I am running:
