The contractor delivered data are to be released, in simplified form, as ASCII comma-separated value (.csv) files. The data format of these files are shown in Tables 2 (Magnetic) and 3 (Radiometric), below.
| Channel | Description | Units |
| X_BNG | Easting (X) BNG (OSGB 1936) | m |
| Y_BNG | Northing (Y) BNG (OSGB 1936) | m |
| Lat | Latitude in WGS84 | m ddd.mm.ss.ss |
| Lon | Longitude in WGS84 | ddd.mm.ss.ss |
| flight | Survey flight number | |
| date | Survey flight date | yyyy/mm/dd |
| Line | Line number | |
| Igrf | International Geomagnetic Reference Field | nT |
| altimeter | Radar altimeter height from surface | m |
| processed_horizontal_gradient | Measured Horizontal Gradient (processed) | nT/m |
| levelled_mag | Total Magnetic Intensity (Levelled) | nT |
| levelled_mag_igrf_corrected | Residual Magnetic Intensity (Levelled) | nT |
| Channel | Description | Units |
| X_BNG | Easting (X) BNG (OSGB 1936) | m |
| Y_BNG | Northing (Y) BNG (OSGB 1936) | m |
| flight | Survey flight number | |
| date | Survey flight date | yyyy/mm/dd |
| Line | Line number | |
| altimeter | Radar altimeter height from surface | m |
| processed_total_count | Final corrected total count | cps |
| processed_potassium | Final corrected potassium | %K |
| processed_uranium | Final corrected uranium | ppm (eU) |
| processed_thorium | Final corrected thorium | Ppm (eTh) |
Additionally, gridded and georeferenced images of standard geophysical derived parameters are also available. These will be released for download via a BGS TellusSW data portal in the near future. Two of the standard images of the data are shown below.
