An alternative term for this final version of the *measured* data could be "Accepted". As there have been no further comments, I will assume that the following revised versions of this set of terms will be good enough for now so that we can move on to the next set of terms. We can always tweak them later if we need to.

• 5-Apr-03 ================================ Edited Data

  ---

  Raw data which has had or is having any kind of mistakes edited out of it, but no systematic instrument corrections have been applied. Comments: 1. The data has been modified since its Raw Data version, but has not yet been certified as Accepted Data.

Accepted Data - Corrected, Uncorrected, No Corrections

---

The input data which is currently the accepted final version of individual Shots and any other measured data: Accepted Corrected if systematic instrument corrections have already been applied to the measurements, Accepted Uncorrected if systematic instrument corrections exist but have not been applied, Accepted No Corrections if no systematic instrument corrections were recorded.
Comments:
1. This data set is approved as now suitable for data reduction, but may or may not be ready for input to any particular survey reduction program depending on the program and what it can accept as input data. 2. The "correction" terms refer to the application of systematic instrument corrections, not to adjustment of measurements in order to close any loops.

Leg Data - Corrected, Uncorrected, No Corrections

---

Accepted Data which provides only a single set of the necessary Measurements for each Leg, possibly by consolidation of several sets of accepted Shot data: Leg Corrected if systematic instrument corrections have already been applied to the Leg data, Leg Uncorrected if systematic instrument corrections exist but have not been applied to the Leg data, Leg No Corrections if no systematic instrument corrections were recorded. Comments:
1. If only one Shot was taken between two adjacent Stations, then Accepted and Leg Data would be the same.

We have now done:

   Field
   Raw
   Edited
   Accepted - Corrected, Uncorrected and No Corrections    Leg - Corrected, Uncorrected and No Corrections The remaining set to do is:

   Reduced
   Adjusted
   Adjusted Leg
I'll send out the first drafts of these in a new thread.
