In the recent thread started by yswami, he asked, and Kent answered this question:


What wasn't specifically addressed was whether one is to use the adjusted coordinates in the data collector control file, when heading back out to expand the network. It seems you would. You'd still have the un-adjusted coordinates in the Star*net file as Kent states above, but in the field, you'd want the new, adjusted coordinates to work from, wouldn't you?

The thing to remember is that you aren't collecting coordinates. You are collecting raw measurements, which you will later reduce to coordinates. So it doesn't really matter which you go out with.

But as a practical matter, and to answer your question, I'd prefer to use the adjusted coordinates from the primary traverse - assuming the residuals from that adjustment were within the range that could be attributed to random imperfections. If you were heading back to the field to troubleshoot a bust I'd stick with the original, unadjusted coordinates.
