Description

The data is a CSV table containing the following columns:

  • station: station ID
  • order: station order
  • point: point ID
  • method: gravity determination method ('absolute' for primary points, 'relative' for secondary points)
  • station_name: point fullname
  • latitude: approximate latitude
  • longitude: approximate longitude
  • elevation: approximate elevation
  • gravity_eff: gravity at effective position
  • ste_eff: standard error of gravity at effective position
  • h_eff: height of effective position
  • tie: gravity differences from the primary (absolute) point
  • ste_tie: standard error of gravity differences
  • a: first-degree coefficient of vertical gravity gradient approximation
  • b: second-degree coefficient of vertical gravity gradient approximation
  • ua: standard error of the first-degree coefficient
  • ub: standard error of the second-degree coefficient
  • covab: correlation coefficient
  • gravity: final gravity value, which is related to point benchmark
  • total_uncert: total uncertainty of the final gravity value
  • expanded_uncert: total expanded uncertainty of the final gravity value

Notes (English)

This version supersedes all previous ones. Previous versions contained errors in the computation of "gravity" column,
