This page lists each table of a hole and its fields, in the order of the project tree. For how to use the tables, see Use the tables.

  • Unit: the unit of the value. Depths are in metres below the ground.
  • Notes: what you can type, the limits, and the AGS 4 heading that the field goes to in an AGS file.
