An example of a Data Tracking Document is shown below for borehole MAR203 at Gard/Marcoule, France. The empty forms were sent to the organisations who supplied information on their site(s) and also used the forms as checklists and general guides to what is needed. The Core Group then evaluated all information received and filled in the Data Tracking Document for each site (areas shaded grey in the example below). For each item, the name of the underlying electronic document was noted (if applicable), together with the references to sources of the information. Very importantly, screening procedures and all changes done to the data were recorded, together with comments.
