Output from Gaussian Process Regression (GPR) on gamma radiation data observations from the reactor hall at the Lancaster University Neutron Laboratory (LUNL).


The file is comma separated, with header row. Data columns are grid positions x and y (in metres), the estimated gamma counts (mean), and the absolute variance estimates, including upper and lower values. The variance can be used as an indicator of confidence in the estimate.

Grid positions correspond to locations of "free-space" identified in the SLAM map created by the robot during the survey mission.
