The response e-mail from OPUS has a lot of information; what information are we looking for to adjust our survey data?

When you’re adjusting survey data, you need to know where the points sit in the plan view. OPUS results give the horizontal position as Northing (Y) and Easting (X), which locate each point on the grid in the chosen datum or projection. These two numbers are what you use to tie your field data to the reference network and compute the necessary adjustments. Elevation or height information is for vertical adjustments, not for aligning the planimetric positions, and while State Plane Coordinates describe a projected system, the actual pieces you work with to adjust are the Northing and Easting values. So, the essential information to extract from OPUS for adjustment is the horizontal coordinates: Northing and Easting.
