Um...how do I know that the data I get back is any good?
there is a link to the 'decoder ring' site. it will tell you what most everything means. try this: opus translation
Look at your peak-to-peak values, rms, etc. Here is a link that explains some of it.
Another good rule of thumb is to look at the "Quality Indicators" and their suggested "good values". Also, the percentage of observations used can be helpful. If a lot of the observations have to be thrown out there could be a problem with the data.

Re-observe. Or check into known control. The statistics are great, but that's the bottom line.
I agree with Norman. Repeat observations.
When I do OPUS sessions, I know I'll be submitting through OPUS-RS so I collect a minimum of two files (15 minutes each), sometimes 3. I will reset the tripod between sessions. At the worst, this will take an hour - time well spent.
